A 403 means the server refused access to the requested resource. The most common cause is incorrect file or folder permissions.
- In cPanel File Manager, set folders to
755and files to644. Never use777. - Confirm an index file (
index.htmlorindex.php) exists in the directory, or directory listing will be blocked. - Check
.htaccessforDeny,Require, or IP rules and temporarily rename it to test. - A ModSecurity rule may be blocking the request — check cPanel ModSecurity or the error log.
If permissions and .htaccess are correct, open a ticket with the blocked URL.
