You don't have permission to access /site/forum/posting.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.
I am definitely allowed to view that page, because I used it to post this
It seems to be connected to using brackets in the title, like so: "REQ Update(2017)".
This gives no issues: "REQ Update today"
But this gives me that page again: "REQ Update(test)"
P.S. I'm using Windows 10 and Firefox 51.0.1(32 bit)
