Understanding the 403 Forbidden Error

The 403 Forbidden Error is a status code that occurs when the server denies access to a particular resource on your WordPress site. This could be due to various reasons, such as incorrect file permissions, issues with the .htaccess file, plugin conflicts, CDN misconfigurations, or problems with hotlink protection. Each of these factors can trigger the 403 Forbidden Error, preventing you from accessing certain areas of your Website.

In the following sections, we'll explain each potential cause in Detail and provide actionable solutions to help you resolve the issue. Without further ado, let's begin with fixing file permissions.

Fixing File Permissions

File permissions play a crucial role in determining who can access, modify, or execute files and folders on your WordPress site. Each file and folder has its own set of permissions indicated by a three-digit number. Normally, these permissions work seamlessly on your WordPress site. However, if they get messed up, it can result in the 403 Forbidden Error.

To view and modify your site's file permissions, you'll need to connect to your server via FTP or SFTP. We recommend using the free FileZilla FTP program for simplicity. Once connected, you can check and adjust the permissions for each file and folder manually. However, this can be time-consuming and impractical.

Instead, you can automatically Apply proper file permissions to all the files and folders inside a specific directory. According to the WordPress codex, the ideal file permissions for WordPress are 644 or 640 for files and 755 or 750 for directories. Only the wp-config.php file should have permissions set to 440 or 400.

To apply these permissions, follow these steps:

1. Right-click on the folder that contains your WordPress site (usually named "public" at Kinsta).
2. Choose "File Attributes" from the drop-down menu.
3. Enter "755" or "750" in the numeric value box.
4. Select "Recurse into sub-directories" and choose "Apply to directories only".
5. Click "OK" to save the changes.

Next, repeat the process for files within the same folder:

1. Right-click on the folder again and choose "File Attributes".
2. Enter "644" or "640" in the numeric value box.
3. Select "Recurse into sub-directories" and choose "Apply to files only".
4. Click "OK" to save the changes.

Finally, manually adjust the permissions for the wp-config.php file by right-clicking on it and setting the permissions to either 440 or 400.

If incorrect file permissions were causing the 403 Forbidden Error, your site should start working again after applying these changes.

Troubleshooting the .htaccess File

For those using the Apache web server (not applicable to Kinsta customers who use NGINX), the .htaccess file can be a potential source of the 403 Forbidden Error. This configuration file allows you to set up redirects, restrict access to your site, and perform other functions. However, even a minor mistake in the .htaccess file can cause significant issues, including the 403 Forbidden Error.

Instead of troubleshooting the .htaccess file directly, a simpler solution is to force WordPress to generate a new, clean .htaccess file. To do this, follow these steps:

1. Connect to your server via FTP.
2. Locate the .htaccess file in the root folder of your WordPress installation.
3. Download a copy of the file to your computer as a backup.
4. Delete the .htaccess file from your server.
5. In your WordPress dashboard, go to "Settings" and then "Permalinks".
6. Click the "Save Changes" button at the bottom of the page without making any modifications.

By doing this, WordPress will automatically generate a new .htaccess file for you. If the old .htaccess file was causing the 403 Forbidden Error, your site should now be accessible.

Deactivating and Reactivating Plugins

If neither file permissions nor the .htaccess file are to blame for the 403 Forbidden Error, the next culprit to investigate is your WordPress plugins. It's possible that a plugin is causing conflicts or compatibility issues, resulting in the error. To identify the problematic plugin, you'll need to go through a process of trial and error.

If you can still access your WordPress dashboard, follow these steps:

1. Go to the "Plugins" section in your WordPress dashboard.
2. Deactivate all your plugins simultaneously.
3. Reactivate the plugins one by one, checking for the presence of the 403 Forbidden Error after each reactivation.
4. Once you encounter the error again, you've found the culprit.

In case you cannot access your WordPress dashboard, you'll need to connect to your server via FTP. Follow these steps:

1. Connect to your server via FTP or SFTP.
2. Navigate to the "wp-content" folder.
3. Locate the "plugins" folder within "wp-content" and rename it to something like "plugins-disabled".
4. Refresh your site and check if the error persists.
5. If the error is gone, rename the "plugins-disabled" folder back to "plugins".
6. Reactivate your plugins one by one, checking for the presence of the error after each reactivation.
7. Once you identify the problematic plugin, consider reaching out to the plugin developer for assistance or find an alternative plugin that serves the same purpose.

By going through this process of deactivating and reactivating plugins, you should be able to pinpoint the plugin causing the 403 Forbidden Error and resolve the issue accordingly.

Temporarily Deactivating CDN

If you're experiencing the 403 Forbidden Error specifically on your assets, such as images, JavaScript, or CSS files, it's possible that your content delivery network (CDN) is causing the issue. To troubleshoot this, we recommend temporarily disabling your CDN and checking if your site functions properly without it.

If you're a Kinsta client, follow these steps:

1. Access your Kinsta site's dashboard.
2. Go to the "CDN" tab.
3. Click the "Disable CDN" button.

Once you've disabled the CDN, check your site to see if it resolves the 403 Forbidden Error. If it does, you may need to review your CDN configuration or troubleshoot any issues with your CDN provider.

Checking Hotlink Protection Configuration

Hotlinking refers to the practice of linking to a resource hosted on someone else's site, inadvertently consuming their bandwidth. To prevent hotlinking, some WordPress hosts or CDN providers offer hotlink protection. When enabled, this feature returns a 403 Forbidden Error when someone tries to access an image or resource hosted on your site from another source.

If you encounter a 403 Forbidden Error on something that should be accessible, it's worth checking if your hotlink protection is configured correctly. Review the settings and ensure that legitimate requests to your site are not being blocked.

To summarize, the steps to fix the 403 Forbidden Error are as follows:

1. Check and fix file permissions.
2. Troubleshoot the .htaccess file.
3. Deactivate and reactivate plugins.
4. Temporarily disable CDN.
5. Verify hotlink protection configuration.

If you have tried all these solutions and are still experiencing issues, it's recommended to contact your hosting provider for further assistance. They will be able to help you identify and resolve the issue causing the 403 Forbidden Error. If you're a Kinsta client, simply open a support ticket, and our expert WordPress engineers will be available 24/7 to assist you.
