Users can no longer see the forum and admins can no longer see the forum or control panel. Instead, we all get the 404 error message: "You don't have permission to access /forum/viewforum.php on this server."
If this has been caused by an IP mod or other security setting being set to block all users, is there a file that can be uploaded to the install folder to rescue the forum, or is it a case of starting from scratch?
Many thanks in advance for help and suggestions
is it a 404 error or the one you posted?
they are different things with different causes and different solutions.
what did you change just before this stated happening?
if the board was working and then stopped, somebody changed something.
