I have a webhierarchicaldatagrid and it is working fine on my local machine but after I deploy it on server it is not expanding the child grids.

It gives Invalid Argument and when I debug it, the error comes in ScriptResource.axd file on line:

this._request.open(this._manager.getHttpVerb(), this._manager.getUrl(), this._async);

In Mozilla it works on some versions but gives out this error on other versions. It is not even expanding the child grids with IE. Can someone please suggest what could be the problem.
