Grid Connector

I’m new in using dhtmlx. I need to show records from a big database so i started from your example named “14_loading_big_datasets/02_50000_paging”. Everithing works fine the grid call the connector php, the php generate the xml but the xml shown in a javascript popup window instead of in the grid. What am I doing wrong ? thx in advance.

Finally I found the solution. There were two extra char at the begining of the xml and that cause the problem.
