OK, here is the link http://www.animalhelpeurope.de/vbforum/forum.php

maybe it's you register popup or your page up button try to disable the guest register popup and let me know if it works and what mod that is and i try to figure out a fix for you.

I disable the guest register popup, but it's still the same. The page up button is installed after the error occurred.

yeah i don't know maybe try this mod VSa - Forums Online CountUp it might work. I don't really know much about javascripts i did not write the code for the countup found it on the internet.

Ok, thanks anyway for the help! The other mod works!
