When I try to make a change in Meta Tags Manager Meta Tags Manager:

Forbidden

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

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
How can I fix this?
thanks

Hello,

Do you have some custom rules in your .htaccess file present, or are you using the default one?

This is really strange problem. Could you contact me at Diese E-Mail-Adresse ist gegen Spambots geschützt! Du musst JavaScript aktivieren, damit Du sie sehen kannst. and send me the access information to your website's administration area, so I can check this problem myself?
Thank you.
