Error popup

Hi, how to avoid the display of error popup?
For us only on console.log is ok.
Thanks!

Hello,
the popup appears when the server returns invalid xml, so an expected solution is to make sure server returns a correct response and preventing an invalid state of the client-side.
But you can also catch this error and redirect it to console:

dhtmlxError.catchError("ALL", function(){ console.log(arguments); });
