How to Fix HTTP 403 Error?

Once encountered a 403 Forbidden, you need to be calm and find the corresponding method. Here we sum up some common solutions for solving this error easily.

Backup Your Site Firstly

Before addressing the 403 error, you firstly need to backup your WordPress site. This practice can eliminate your headache at the point of website breaking. After all, to deal with this HTTP error, you might be required to work with your core files, folders, plugins and many more in a deep manner.

Check and Modify the File Permissions

It is a common sense that all the WordPress files and folders have the access permissions to control who have the right to check the content. In this case, if your file permissions are set to the wrong value, the 403 error can happen, for the web server may think that you do not have the access freedom so as to refuse the requests.

To figure out this part, you need to leverage an FTP manager that can connect to your WordPress site. After accessing it using your exclusive login credential, you should go over the installation folder of WordPress by double clicking the public_html folder. This way, you can find all the essential files and folders.

Now, you just need to select them, right click your mouse and click the File Permissions button.

Change File Permissions

Before clicking the “OK” button, you need to tick the checkbox that applies the changes to all the sub-directories.

Fix the Corrupted .htaccess File

To be frank, once your .htaccess file is corrupted, there might be a lot of issues happened on your site, and the 403 error is one of them. However, the good news is that the process of fixing such a corrupted file is quite simple that only takes you a few minutes.

To check whether this file is wrong or not, you can firstly locate it from the WordPress root folder using either the FTP client or the File Manager tool available from the cPanel control panel. After that, you need to download this file to your local computer, and then, delete from your web server.

Now, you can go back to your site to figure out whether this error is removed. If so, it means your .htaccess file is in the wrong situation. In this case, you’d better generate a new one.

To create a fresh copy, you simply need to jump into the Settings page of your dashboard and click the Permalinks option. If there is nothing you want to change, you can directly click the Save Changes button. After that, a new .htaccess file is created and uploaded to your site server automatically.

Clear Cache and Cookies

Sometimes, you have already fixed this 403 error. However, the error may still exist due to the browser cookies and cache data. In this case, you need to clear them to make sure that your method truly takes effects.

In addition, if your website is powered by a cache plugin for the performance improvement, you’d better delete all the cached pages and turn off the caching function for a while.

Deactivate Your Plugins and Themes

Here, you need to know that some compatibility issues and the faulty settings of your plugins and themes may also cause the 403 error. In this case, you should deactivate all of them to figure out whether this error lays on this aspect. If the 403 error disappears, you can start the boring task of picking up the real trouble maker.

Here, to deactivate your plugins and themes altogether, you simply need to locate your plugin folder and theme folder using the File Manager or the FTP. After that, you can change their names to anything you like. This way, WordPress cannot find your plugins and templates so as to result in the deactivation.

  • Contact your web hosting provider. Sometimes, this error might be caused by some wrong server configurations and security settings determined by your web host. In this case, you’d better contact your hosting company to check if there is something wrong.
  • Fix the index.php file. Many webmasters claim that they fix this issue simply by deleting the old index.php file from the root directory and uploading a totally new one.
  • Install a new copy of WordPress. This can be your last choice if you have tried a large number of methods but none of them bring your WordPress site to the normal condition.
  • Check the IP deny rules. It is possible that you are blocking your IP in the web server. If so, you’d better unblock it using your control panel.
