How to fix 403 Error Messages?

Updated: 28 September 2026 · Applies to: cPanel & WHM 138 (Jupiter theme) and Apache 2.4 (.htaccess)

"403 Forbidden" means the server refused the request. Check these causes in order:

1. Missing index file: if a folder has no index.html or index.php and listing is turned off, you get 403. Upload an index file.
2. Permissions: files should be 644 and folders 755. Folders set to 700, or files to 600, can cause 403.
3. .htaccess rules: look for Deny from, Require or IP blocks in .htaccess files; rename the file temporarily to test.
4. IP Blocker or firewall: check Security › IP Blocker. If only you get the error, your IP may be blocked after failed logins; open a ticket with your IP.
5. ModSecurity: if a form or admin action is blocked, see "Disable ModSecurity in cPanel" and ask us to adjust the rule rather than switching protection off.

The error log (Metrics › Errors) usually names the exact reason.
