Hello. I´m using the K2-1.0.2b Version because i can set the "Default (Frontpage) Layout".
And there is my problem. There are only 9 of my 11 Category's to see. Tried different things
but not more than 9 will be shown. There isnt any error to see.
I hope that anyone can help me ;)

Thanks for your help Altan ;)
Someone gave me the Tip, here for all a solution if they have the same problem:

components/com_k2/models/default.php at line 31
$limit = JRequest::getInt('limit', 9);
