406 Not Acceptable Error
 

Hi there.
I'm requesting help from any of the guru's here. =)

I'm getting this 406 error in my forum. A member posted a thread. Everytime I click page 2 or page 3 or page 4 or even "last", this error pops up. The weird thing is that it happens only in this one thread. Anyone have any clue what might be wrong?

406 Not Acceptable

Not Acceptable

An appropriate representation of the requested resource /showthread.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.

Does the title of the thread contain more than 2 dots at the end?
Else remove those and try again. There is a bug when adding too many dots at the end of a thread title it gives an error when going to an other page.

Have the same issue, but there are no dots at the end. I did change the title an little bit and that did seem to help with the issue.
