Posts with links

[malag]

When I write a post with link (links), I receive such an error:

"Not Acceptable
An appropriate representation of the requested resource /newthread.php could not be found on this server."

But when I write a typical post without any links, everything is all right.
The problem probably resulted from transfering board to the new server.
Where is a problem, and how can I repair it?"

Disable your modifications and try again.
