I tried installing an ezportal module onto my website and it gave me this:
Forbidden

You don't have permission to access /index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Does anybody know how to fix this issue?
