Laravel datatables draw parameter allways 0

Question

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!
