How to Stop WordPress From Overwriting Your .htaccess File

As a WordPress expert with over 15 years of experience, I’ve seen my fair share of .htaccess headaches. One of the most common questions I get is “How do I stop WordPress from overwriting my .htaccess file?” It’s a valid concern, especially if you’ve added custom code to your .htaccess file. This article will guide you through the steps to protect your custom code and prevent accidental overwrites.

The .htaccess file is a powerful configuration file that controls various aspects of your WordPress website. It acts as a set of rules that your hosting server uses to interpret and handle requests to your site. WordPress, along with various plugins, often modifies this file to implement specific features. For instance, WordPress uses .htaccess to store its permalink settings, while caching plugins like W3 Total Cache might use it to configure their optimization rules.

When you add custom code to your .htaccess file, for example, to set up redirects, block specific IP addresses, or improve website security, it’s essential to ensure that WordPress or your plugins don’t overwrite it. Overwriting can cause your custom settings to be lost, leading to unexpected website behavior or security vulnerabilities.

Let’s dive into the details and explore how to protect your custom .htaccess configurations.

Understanding .htaccess and WordPress’s Role

The .htaccess file is a hidden file located in the root directory of your WordPress installation. It’s essentially a collection of directives (lines of code) that tell your web server how to handle requests for your website. Here’s how WordPress uses .htaccess:

1. Permalinks

WordPress uses .htaccess to store its permalink settings, which determine how your website URLs look. For example, if you want to use a custom permalink structure like “example.com/blog/my-post-title” instead of the default “example.com/?p=123,” WordPress modifies the .htaccess file to reflect this change.

2. Plugin Settings

Some WordPress plugins, particularly those related to caching, security, or optimization, also modify .htaccess to implement their features. For instance, a caching plugin might add directives to your .htaccess file to enable browser caching, while a security plugin might add rules to block suspicious requests.

3. Custom Code

You can add your custom code to .htaccess to control how your website works. This can include:

Redirecting visitors: Redirect users from old URLs to new ones.
Blocking specific IP addresses: Prevent access from specific IP addresses, often used to block malicious bots or spammers.
Improving website security: Implementing security measures like preventing hotlinking or limiting file access.
Setting up custom error pages: Displaying custom error pages for specific error codes (e.g., 404 not found).

How to Stop WordPress From Overwriting Your .htaccess Rules

Here are the key methods to prevent WordPress or plugins from overwriting your custom .htaccess code:

1. Don’t Modify Code Inside the WordPress Markers

WordPress includes markers in .htaccess to clearly delineate the area where it stores its permalink settings. These markers are:

# BEGIN WordPress
# END WordPress

The lines of code between these markers are automatically generated by WordPress and will be overwritten whenever you change your permalink settings. It’s crucial to avoid adding your custom code within these markers. Instead, place your code above the # BEGIN WordPress marker. This way, your code will be safe from WordPress’s overwrites.

2. Don’t Modify Code Inside Your Plugins’ Markers

Plugins also use markers to separate their settings within the .htaccess file. For instance, the W3 Total Cache plugin might use the following markers:

# BEGIN W3TC Browser Cache
# END W3TC Browser Cache

Never add your custom code within the markers used by plugins. Plugins will overwrite these sections when their settings are changed. Always place your custom code either above or below the plugin markers.

3. Creating Markers for Your Custom Code

If you’re concerned about a rogue plugin potentially overwriting your custom code, you can add your own markers to your .htaccess file. For example, you can use these markers:

# BEGIN MyCustomCode
# END MyCustomCode

Place your custom code between these markers. It’s generally safe to assume that plugins and WordPress will not overwrite code within these custom markers. However, it’s always best to double-check and test after making any changes to .htaccess.

4. Understanding WordPress Rewrite Rules

If you need to manually add custom rewrite rules to your .htaccess file, ensure you understand how WordPress handles rewrite rules. WordPress uses a specific pattern for its rewrite rules, and it’s crucial to adhere to this pattern to avoid conflicts.

Here’s a common example of a WordPress rewrite rule:

RewriteRule ^category/([^/]+)/?$ index.php?category_name=$1 [L,QSA]

In this rule:

^category/([^/]+)/?$: Matches a URL that starts with “category/” followed by any character except “/” (captured in group $1) and ends with an optional “/”.
index.php?category_name=$1: Redirects the request to index.php, passing the captured group $1 as the category_name parameter.
[L,QSA]: Specifies flags for the rule. “L” indicates that this is the last rule to be applied, and “QSA” means that any existing query string parameters should be preserved.

If you need to create custom rewrite rules, ensure they don’t conflict with WordPress’s existing rules and follow the same pattern for structure and flags.

How to Stop WordPress From Modifying .htaccess

In some cases, you might want to completely prevent WordPress from modifying your .htaccess file. This is usually done for advanced scenarios where you want to take full control of .htaccess or when you are manually managing permalinks. However, it’s important to understand the risks involved and be cautious when modifying file permissions or using code snippets.

1. Stopping WordPress From Changing .htaccess Using File Permissions

One way to prevent WordPress from writing to .htaccess is to make the file read-only. This means that neither WordPress nor any plugins will be able to modify its contents. However, you’ll also be unable to edit the file yourself, so this method requires caution.

Here’s how to change file permissions using an FTP client like FileZilla:

Connect to your server: Log in to your FTP client and connect to your WordPress hosting server.
Locate the .htaccess file: Navigate to the root directory of your WordPress installation, where you’ll find the .htaccess file.
Change file permissions: Right-click the .htaccess file and select “File Permissions” or a similar option.
Set permissions to 444: In the file permissions dialog box, enter “444” in the “Numeric Value” field. This sets the file to read-only.
Confirm changes: Click “OK” to save the changes.

If you need to modify the .htaccess file later, you’ll need to temporarily change the file permissions back to 644 (read/write) to edit it. Once you’re finished, set the permissions back to 444 to prevent accidental overwrites.

2. Stopping WordPress From Changing .htaccess Using Code

Another approach is to use a code snippet that disables WordPress’s ability to modify the .htaccess file. This method is more suitable for experienced users who are comfortable working with code and understand the potential consequences of modifying core WordPress files.

Add the following code snippet to the end of your wp-config.php file. The wp-config.php file is located in the root directory of your WordPress installation. Remember to back up your wp-config.php file before making any changes.

add_filter('got_rewrite', '__return_false');

This code snippet disables WordPress’s rewrite rules, effectively preventing it from modifying the .htaccess file. However, keep in mind that this will also disable WordPress’s permalink features. If you need to change your permalinks, you’ll need to do it manually by editing the .htaccess file directly.

Error Messages When WordPress Can’t Change .htaccess

If you try to change your permalink settings while your .htaccess file is set to read-only, you’ll see error messages in the WordPress admin area. These messages help you understand that WordPress is unable to modify the .htaccess file.

1. “You Should Update Your .htaccess File Now”

This message appears at the top of the Settings » Permalinks page. It indicates that WordPress has attempted to modify the .htaccess file but was unable to do so because the file is read-only.

2. “Your .htaccess File Is Not Writable”

This message appears at the bottom of the Settings » Permalinks page. It confirms that the .htaccess file is not writable and displays the rewrite rules that WordPress attempted to add to the file. You can manually paste these rewrite rules into your .htaccess file, but remember to temporarily change the file permissions back to 644 (read/write) before editing the file. Once you’ve saved your changes, set the file permissions back to 444 (read-only) to prevent accidental overwrites.
