Language gives 404 error messgae

Hi!

When I try to save something in the languages file it gives me a 404 error message:


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.


Thanks

EDIT: It was because I was trying to save the new wording with an = sign. Changed it to equals and works now
