Prevent WordPress from Overwriting Your .htaccess File: Essential Tips and Tricks

A reader recently inquired about how to stop WordPress from overwriting their custom code in the .htaccess file. This concern is quite common, as WordPress and its plugins frequently modify this important configuration file.

If you’ve added custom code to your .htaccess file, it’s natural to be concerned about it being overwritten or erased. Safeguarding this code is crucial for maintaining your site’s performance and security.

In this article, we will provide you with detailed steps to prevent WordPress from overwriting your .htaccess file. By following our guidelines, you can protect your custom code and ensure that your website operates seamlessly without any disruptions.

Why Does WordPress Modify the .htaccess File?

The .htaccess file is a vital configuration file that contains essential settings for your WordPress website. It includes rules that instruct your hosting server on how to manage your site.

WordPress utilizes the .htaccess file to save its permalink settings. Whenever you update or regenerate your permalinks, WordPress will automatically replace the previous settings in .htaccess with the new ones.

Certain WordPress plugins, like W3 Total Cache, modify the .htaccess file to manage caching and optimization features.

You can also make personalized adjustments to your .htaccess file to enhance your website’s functionality. This includes adding custom rules to secure your admin area, protect against hackers, set up redirects, block suspicious IP addresses, and more.

Some users worry that their custom rules in the .htaccess file might be erased when WordPress updates it with new settings. Others prefer to manually edit .htaccess and prevent WordPress from making any changes.

How to Prevent WordPress From Overwriting Your .htaccess Rules

The good news is that if you understand the functionality of the .htaccess file, you can ensure that your custom rules remain intact.

This is because the sections of the file that WordPress or your plugins will modify are clearly indicated. Just ensure that you do not insert any code within those sections.

Avoid Altering Code Within WordPress Markers

As previously mentioned, WordPress utilizes the .htaccess file to manage settings for an SEO-friendly URL structure. The code stored in this file will be automatically updated and overwritten whenever you adjust your permalink settings.

In the screenshot below, you can see that WordPress stores this information between two markers: # BEGIN WordPress and # END WordPress.

Pay attention to the warning within those markers:

The directives (lines) located between ‘BEGIN WordPress’ and ‘END WordPress’ are generated dynamically and should only be modified through WordPress filters. Any alterations made to the directives between these markers will be overwritten.

This indicates that WordPress will not overwrite or alter any code you add outside of these markers. Users typically place their custom code at the top of the file, above the # BEGIN WordPress marker.

Avoid Altering Code Within Plugin Markers

When a plugin saves its settings to the .htaccess file, it does so between specific markers that look like # BEGIN Plugin and # END Plugin.

For instance, if you install and configure the W3 Total Cache plugin to enhance your website’s speed and performance, it will insert rules into the .htaccess file between # BEGIN W3TC Browser Cache and # END W3TC Browser Cache markers.

These rules may be overwritten whenever you adjust the plugin’s settings, so be cautious not to insert your own custom .htaccess rules between those markers.

Establishing Markers for Your Custom Code

In rare instances, a poorly designed plugin may alter code outside of its # BEGIN and # END markers. However, it typically does not change code located between the markers utilized by WordPress or other plugins.

If you’re worried about a problematic plugin overwriting your custom code, you can insert your own markers in the .htaccess file.

For instance, you can add # BEGIN MyCustomCode and # END MyCustomCode markers at the beginning of the .htaccess file, allowing you to place your custom rules between these markers.

If you also want to append code at the end of .htaccess, you can create a separate set of markers. Just ensure they have unique names, such as ‘MyCustomCodeTop’ and ‘MyCustomCodeBottom’.

How to Prevent WordPress From Altering .htaccess

Now that you know how .htaccess functions, you can be assured that your custom code will remain intact, unaffected by WordPress or its plugins.

However, some developers and advanced users prefer to completely prevent WordPress from altering .htaccess.

For example, you might want to manually set permalinks by entering the settings directly into .htaccess. In this scenario, it’s essential to avoid conflicts by preventing WordPress from saving its own permalink settings to the file.

We advise against this unless you are experienced, as it may result in unforeseen issues. Nonetheless, it can be achieved by modifying the file’s permissions or utilizing code.

Preventing WordPress from Modifying .htaccess with File Permissions

To prevent WordPress from altering the .htaccess file, you can set it to read-only. This involves changing the file permissions through an FTP client or the file manager offered by your WordPress hosting service.

The .htaccess file is located in the root directory of your WordPress installation. Right-click on the file and select ‘File permissions’ to proceed.

A pop-up will appear, allowing you to modify the file’s attributes.

The default permission setting is 644. You can change it to 444 by entering this value in the ‘Numeric value’ field or by ensuring that only the ‘Read’ options are selected.

After clicking the ‘OK’ button, the file will be set to read-only and cannot be altered.

Keep in mind that this will also prevent you from writing to the file. If you need to make changes, you will have to temporarily revert the file permissions back to 644.

Preventing WordPress from Modifying .htaccess with Code

An alternative method is to use a code snippet that instructs WordPress not to write to the .htaccess file. This approach is beneficial if you want to stop WordPress from modifying .htaccess while still allowing your plugins to function.

Note:Modifying core WordPress files can be risky. Even minor errors can lead to significant issues on your website. Therefore, we advise this approach only for experienced users.

To prevent WordPress from overwriting your .htaccess file, simply add the following code snippet at the end of your wp-config.php file. For assistance, refer to our guide on editing the wp-config.php file in WordPress:

add_filter('got_rewrite', '__return_false');

After implementing this change, WordPress will stop writing to the .htaccess file.

Error Message When WordPress Fails to Modify .htaccess

If you attempt to update your permalink settings while .htaccess is set to read-only, an error message will appear.

At the top of the Settings » Permalinks page, you will see a notification stating, ‘You should update your .htaccess file now.’

This indicates that WordPress was unable to alter the .htaccess file.

This is usually the desired outcome. However, if you want to manually add the WordPress permalink settings to .htaccess, you will need to do so yourself.

At the bottom of the Settings » PermalinksOn this page, you may encounter an error message indicating that your .htaccess file is not writable. Below that, you will find the necessary rules to be added to the .htaccess file.

To implement those settings, you will need to temporarily change the permissions of the .htaccess file back to 644 to allow editing. After making the changes, paste the rules between the WordPress BEGIN and END markers, replacing any existing code.

Once you have completed the changes, reset the permissions back to 444 and save the file. It will be set to unwritable again.
