The 403 Forbidden error is a HTTP status code indicating that the server understands the request, but it refuses to authorize it. This error message typically occurs when there is a problem with the permissions on your website’s files and folders. Here are a few things you can try to troubleshoot the issue:
- Check file permissions: Make sure that the server has the correct permissions to read and execute the files and folders on your website. The recommended permissions for most files is 644 and 755 for most directories.
- Check .htaccess file: The .htaccess file controls many important settings for your website, including permissions. Make sure that the .htaccess file is not causing the problem by renaming the file and checking if the problem is solved.
- Check if mod_security is causing the problem: mod_security is a security module for Apache servers that may block certain types of requests. Contact your hosting provider to check if mod_security is causing the problem and ask them to disable it.
- Check for plugin conflicts: Some plugins may conflict with each other and cause the 403 Forbidden error. Try disabling all of your plugins and then enabling them one by one until you find the plugin that is causing the problem.
- Contact Namecheap support: If you are hosting your website with Namecheap, contact their customer support to see if they can help resolve the issue. They can check your account’s settings and also check server-side issues that could be causing the problem.
It’s important to note that these suggestions are general troubleshooting steps and the actual cause of the problem could be different from what I’ve listed. I recommend you to check the website documentation and support channel for further troubleshooting.
