Forum Link Not Working (Fatal Error)

[topianno]

Hi,
I am having a problem entering a "Forum Link" on my forum. The system fails to forward to the user to the link you input and creates a fatal error.

I am referring to a "Forum Link"
(Entering a URL here will cause anyone clicking the forum link to be redirected to that URL)

Whenever I add a link the following error occurs.

Not Acceptable

An appropriate representation of the requested resource /forumdisplay.php could not be found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
Apache Server  Port 80

The URL the link is calling is this weird link: "/forumdisplay.php?178-Regional-Support-Groups"

Has anyone else had this problem? Anyone know of a fix? This problem started when I upgraded to 4.0.

Thanks ahead of time!

I figured it out. For some reason the system didn't like the characters I had listed in the title of the Forum. When I changed the title, it worked fine. Strange.
