You don't have permission to access /index.php/penamas/login/signIn on this server. Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request

Why is error logging in as administrator? Please help? But if I login as author succeed.

Hi @ceperlan,

Check your server’s error logs; I suspect there’s a tool like mod_security running on your server that’s intercepting the request erroneously before OJS can get to it.
