Apparently the introtextword limit (K2-> itemlist -> category) doesn't work with my JoomFish. The original texts have a limited intro text, the translated text shows the whole article.With JoomFish I don´t see an option for the introtext word limit, maybe this is the reason? I have cleared the cache, didn't help.Who knows how to do this? Thanks in advance!

Solved it! :D

This is the solution:
