Laravel datatables draw parameter allways 0

问题:

In my Laravel application, I'm using Yarja datatables. Local it works perfectly. On the test server, it works also perfect. But on the customer server, paginate, sort and search doesn't work. I found out, that the request contains a draw var and also the repsonse. This var is counted from 1 up. On the test server the draw-var in request is always the same like in the response. But on the customer server, the draw-var int the request is counted correctly, but in the response the draw-var is allways 0.

What can be the error? I have no Idea where i have to search. Every help is very welcome!
