Mod Rewrite and Pagenation ... a problem

Hi there and sorry for my bad english 

I've " UTF-8 CuteNews 9.0.1" working (works great btw! )
And I installed this Hack: https://cutephp.com/forum/index.php?showtopic=32005

But when I will click on the number at the pagenation it wont work:

postpage/5&ucat=&archive=&subaction=&id=&

But, and that's the funny thing: the arrows work 

May you would throw an eyeball (or two) of it: http://www.portman-natalie.de/

Would be happy for a solution

Greetings from germany
