The plugin install went ok but when I access the WHMCS Integration through the wordpress admin panel it ask me for
Remote WHMCS Host:
Default Content Page:
and when I put those in and click "Save Settings" it gives me a
You don't have permission to access /aa/wp-admin/admin.php on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
How do I fix this?
