Пытаясь поставить тему по умолчанию или сменить звание пользователю.

Я получаю ошибку: 

Forbidden

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

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

 

Так же поулчаю её очень часто, когда пытаюсь что либо сделать.

Что делать?

Так же форум переносил на новый домен и хостинг.

После чего сия проблема появилась.

Может я сделал что-то не так при переносе?

Так же лог ошибок Apache:
