In 2019, WordPress introduced a new content editor named Gutenberg, replacing the old classic editor. This innovative editor utilizes blocks to create and manage content within WordPress.
Despite its advantages, users may encounter frustrating issues while using the block editor. Even at CanadaCreate, we’ve faced several challenges with this tool.
In this article, we will outline solutions to the most common problems associated with the WordPress block editor, helping you enhance your content creation process.
What Is the WordPress Block Editor?
The WordPress block editor, also known as Gutenberg, was launched with the WordPress 5.0 update. Since its release, WordPress has continually enhanced the editor by introducing new features and improvements.
This editor offers greater customization options compared to the Classic Editor. You can use various blocks to insert different elements into your content without needing to modify any code for styling or appearance changes.
It aims to provide a real-time preview of how your posts and pages will appear by replicating the fonts and colors of your chosen WordPress theme.
For instance, you can utilize an Image block to incorporate photos into your blog posts, along with options for image style, size, alignment, and more through the block settings.
Many WordPress plugins enhance the content editor by adding their own blocks, allowing you to easily incorporate elements like forms, social media feeds, and tables of contents with just a few clicks.
However, the block editor is not without its flaws. As with any WordPress plugin, you may encounter various errors or bugs.

1. How to Fix the WordPress Block Editor Not Working Error
A frequent problem users encounter is the ‘WordPress block editor not functioning properly.’
This issue can arise for several reasons, such as an outdated theme, a malfunctioning plugin, or other technical glitches.
The block editor may also fail to work if there is a misconfigured setting on your site, like disabling the visual editor in the user profile.
You can verify this by navigating toUsers » Profilein your WordPress dashboard. Make sure that the option ‘Disable the visual editor when writing’ is unchecked.
If the issue continues, try deactivating all plugins on your site. This will help eliminate any conflicts that might be preventing the block editor from functioning.
Another solution is to update your WordPress theme. An outdated theme can lead to the block editor malfunctioning. Check out our guide on how to update your WordPress theme without losing data and customization.
2. WordPress Block Editor Frequently Crashes
Another prevalent issue some users experience is unexpected crashes of the WordPress block editor.
If the editor crashes, you will see a message stating ‘The editor has encountered an unexpected error.’ WordPress will then present three options: attempt recovery, copy post text, or copy the error details.
This issue can arise from several factors. For example, a plugin may disrupt the block editor, or your WordPress version might be outdated.
To resolve this, deactivate all plugins and then reactivate them one at a time. Alternatively, switch your WordPress theme to a default option, such as Twenty Twenty-Four, to determine if the issue continues.
If the problem persists after checking your plugins and theme, consider updating your WordPress version and clearing the WordPress cache.
3. Fix the Invalid JSON Error in the Content Editor
When you try to update a blog post or page, you may encounter an error message that says ‘The response is not a valid JSON response.’
WordPress continuously communicates with the website server in the background while you edit a post. This error occurs when WordPress does not receive a response from the server, or the response is not formatted as JSON.
Here are several potential causes for the invalid JSON error and how to resolve them:
- Verify WordPress URLs in SettingsEnsure that both the WordPress Address and Site Address in your site’s settings are accurate. Navigate to the Settings » General section and confirm that the URLs match. A discrepancy in the Site Address could lead to a JSON error.
- Adjust Permalink Settings in WordPressIn WordPress, you can configure SEO-friendly URLs for your posts and pages. However, incorrect settings may hinder the block editor’s ability to produce a valid JSON response. Be sure to select the appropriate permalink structure.
- Review WordPress .htaccess File SettingsThe .htaccess file serves as a configuration file in WordPress for managing SEO-friendly URLs (permalinks). Typically, WordPress will automatically regenerate and update this file. However, incorrect configurations or outdated .htaccess files can lead to JSON errors.
- Examine REST API Debug LogsThe REST API is a collection of protocols that WordPress uses to interact with your site’s server. A JSON error may indicate that the REST API has encountered an issue. You can investigate this by checking the REST API logs on the Site Health page in WordPress.
- Consider Deactivating All PluginsA conflict between various WordPress plugins can lead to an invalid JSON error. To troubleshoot, deactivate all plugins on your site and check if the error persists.
- Return to the Classic EditorIf the JSON error remains unresolved, consider switching back to the Classic Editor in WordPress. This traditional content editor does not depend on the REST API for JSON responses from your server.
For a detailed explanation of these solutions, please refer to our comprehensive guide on fixing the invalid JSON error in WordPress.
4. Fixing the ‘Updating Failed’ or ‘Publishing Failed’ Error
Another error you may encounter when trying to update or publish a blog post or page in the WordPress block editor is: ‘Updating failed. You are likely offline.’
This issue arises when the WordPress REST API is unable to connect with the WordPress database.
When the block editor cannot send or receive requests from your WordPress hosting database, various features of your site, including the block editor, may not work properly.
The REST API may become unresponsive if you are not connected to the internet or have lost your connection. To resolve this issue, ensure your internet connection is stable, then attempt to update or publish your page again.
In addition, you can navigate to Tools » Site Health in your WordPress dashboard to access the REST API logs. If there is a problem with the REST API, it will be highlighted in the ‘recommended improvements’ section.
The error log will provide details about what occurred with the REST API and may offer insights into the potential causes of the issue.

5. Adjusting Space Between WordPress Blocks
While designing custom pages and posts with the WordPress block editor, you might find that there is either too much or too little space between blocks.
Typically, your WordPress theme dictates the spacing. However, the block editor also provides options to customize your page layout for an enhanced user experience.
For example, you can insert a Spacer block to create blank spaces. Simply click the ‘+’ button and add the Spacer block wherever needed in your content.
This allows you to insert extra space between blocks.
WordPress also enables you to modify the size of the spacer block. You can increase or decrease its size by dragging the block up or down.
To eliminate extra blank space between blocks, you can add custom CSS to your WordPress theme or utilize a CSS plugin like CSS Hero.
This plugin allows you to modify your website’s CSS without needing to edit the code directly. It provides various spacing options to help you adjust the blank space between blocks.
You can also use SeedProd to design a custom page in WordPress, giving you complete control over the layout and aesthetics.
For more information, please refer to our guide on adding or removing blank space between WordPress blocks.
6. Copy and Paste Content Without Formatting Issues
Have you ever experienced unwanted formatting when copying and pasting content from a desktop application or a web page into the block editor?
You may notice that the font and colors of the pasted content do not align with your WordPress theme. This issue often arises when using Microsoft Word or Google Docs to create content before pasting it into the block editor.
To maintain the original formatting, consider using heading styles from Word and Google Docs. This approach allows WordPress to automatically recognize the headline level when you paste the content into the block editor.
Additionally, it’s important to review the HTML code of your page or post after pasting content. In the WordPress block editor, select a block and click on the three vertical dots menu.
From the dropdown menu, choose the ‘Edit as HTML’ option.
This will help you identify any formatting issues, such as incorrect bold or italic text, unwanted characters, and more.
For further information, check out our guide on how to copy and paste in WordPress without formatting problems.
7. Resolve Image Upload Issues in WordPress
You may encounter an error when trying to upload images in the WordPress block editor, which is a common issue.
This error typically arises from incorrect file permissions. Your website files are stored on your web hosting service and need specific file and directory permissions to function properly.
If the permissions are not set correctly, it can hinder WordPress from accessing and uploading files to the hosting server. Consequently, you may find that images are missing from the media library after uploading, or you might see an error message that states:
‘Unable to create directory wp-content/uploads/2019/04. Is its parent directory writable by the server?’
To resolve this issue, you need to adjust the file permissions. Use an FTP client to access the /wp-content/ directory. Right-click on the folder to change its file permissions.
Refer to our comprehensive guide for step-by-step instructions on how to resolve the image upload issue in WordPress.
8. Resolving the HTTP Image Upload Error
One common problem you might face while uploading images in the WordPress block editor is the HTTP error.
When you upload images to the Media Library, WordPress may display a generic ‘HTTP error’, preventing you from previewing the image.
Several factors could lead to this issue, and the error message often lacks specific details about the underlying cause.
To address this, you can try several solutions. Start by waiting a few minutes and then attempt to reupload the image, as your server may be experiencing temporary issues like high traffic or limited resources.
Additionally, consider increasing the WordPress memory limit to avoid memory-related HTTP errors. You can also try changing the image editor library used by WordPress and modifying the .htaccess file.
If your login session has expired, you may resolve this issue by navigating to the login screen and re-entering your username and password.
For a comprehensive overview of each solution, refer to our guide on fixing the HTTP image upload error in WordPress.
9. How to Resolve Missed Schedule Post Errors in WordPress
Did you know that WordPress includes a built-in feature for scheduling your blog posts?
Within the WordPress content editor, you can set the date and time for your blog posts to be published. However, there are times when your scheduled posts may not go live as planned.
The primary cause of this issue often stems from the WordPress hosting environment or conflicts with plugins. WordPress utilizes a system called ‘cron’ to automatically publish posts at designated times.
If a plugin or your hosting server interferes with the cron jobs, it can result in missed schedule post errors in WordPress.
You can resolve this problem by verifying the timezone settings of your WordPress site. It’s possible that the timezone set for your site does not align with your desired scheduling timezone.
Simply navigate to Settings » General in the WordPress admin panel and scroll down to the Timezone section.
To resolve this issue, consider clearing your WordPress cache and increasing the memory limit.
Check out our comprehensive guide on fixing the missed scheduled post error in WordPress.
10. How to Fix Alignment Problems in the WordPress Block Editor
A frequent issue in the WordPress block editor is improper alignment of your content and images.
For instance, if you center-align a bullet list in a blog post, it may still display as left-aligned in the block editor. Similarly, an image block that is center-aligned might show up aligned to the left or right.
If you have the Gutenberg plugin activated on your WordPress site, it may lead to block alignment issues. We suggest deactivating the Gutenberg plugin to see if that resolves the problem.
Another option is to add this custom CSS code to center-align the text:
.has-text-align-center {
text-align: center;
}
You can also refer to our guide on adding and aligning images in the WordPress block editor.
11. How to Fix Incorrect Facebook Thumbnail Issues
Have you ever encountered incorrect post thumbnails when sharing an article on Facebook?
This issue may arise from conflicting plugins, problems with your content delivery network (CDN), or the absence of Open Graph meta tags for Facebook.
While this problem doesn’t appear directly in the WordPress block editor, you can set an Open Graph image for Facebook using the content editor.
To resolve this issue quickly, you can use the All in One SEO (AIOSEO) plugin, which is the top SEO plugin for WordPress, helping you optimize your site for search engines and social media.
After activating the plugin, an AIOSEO Settings meta box will appear in the WordPress content editor. Navigate to the ‘Social’ tab.
Then, scroll down to the ‘Image Source’ section.
In the dropdown menu, select the image you want to display on Facebook and other social media platforms when your article is shared.
You can refer to our guide on resolving the Facebook incorrect thumbnail issue in WordPress and discover additional solutions.
12. Resolving Facebook and Instagram oEmbed Issues
Another issue related to social media in the block editor is integrating Facebook and Instagram content into your WordPress site.
Previously, embedding posts from Instagram or Facebook in WordPress was straightforward. However, Facebook has updated its oEmbed functionality.
Currently, you cannot embed videos, images, updates, and other content directly in WordPress. Instead, it will display only a plain URL.
You can resolve this issue by using a social media plugin for WordPress, such as Smash Balloon. This plugin allows you to easily embed content from Facebook and Instagram using oEmbed and display social media feeds on your website.
For further information, please refer to our guide on resolving Facebook and Instagram oEmbed issues in WordPress.
13. Unable to View Embedded Content Preview in Block Editor
This issue emerged with the release of WordPress 5.7. When embedding videos from YouTube and Vimeo or adding audio from Spotify and SoundCloud, the preview would not display in the block editor.
Instead, you would see messages like ‘Preview is not available’ or ‘This block has encountered an error and cannot be previewed.’ The primary reason for this issue was the default lazy loading feature.
In WordPress 5.5, iFrames were set to lazy-load by default, meaning that embedded content, such as images, would not load until a visitor scrolled to that section of the page.
To resolve this issue, simply update your WordPress version. The bug has been fixed in later releases. If you’re using version 5.7 or earlier, we strongly recommend upgrading to the latest version of WordPress.
