Update from 4.0.3 to 4.1.3 fails

Hello everyone,

I wanted to upgrade my grid to the newest version simply by replacing the JavaScript Codebase and the CSS-file. But this failed - after deploying it to the server and reloading the page it always gives me the JS-Error on clientside that dhtmlxError and dhtmlxAjax is not known.

I downloaded the whole Suite. What is going wrong here?

Please, try to use the dhx4.ajax instead of dhtmlxAjax:
docs.dhtmlx.com/ajax__migration.html
and onLoadXMLError event instead of dhtmlxError
docs.dhtmlx.com/api__dhtmlxajax_ … event.html
