Only one small important problem..

I've installed VBSEO on Article Exchange Forum - Powered by vBulletin and it works great for all of the subpages.. the only exception is that I get an error when I click on one of the new posts.. like this one.
Superman - Article Exchange Forum

BUT if I manually remove the "-new-post" it works. like this:
Superman - Article Exchange Forum

Can anyone help me with this?

Thank you.

Your link with -new-post on the end works fine for me. What error are you seeing?

I'm am getting a blank page.. lol..

I just check my other PC, and found that it works on that one.. weird.
Thanks anyway..
Cheers!
