    Hi,

    My hosting server went down recently and since it was restored, I am unable to drag and drop controls on the page editor.  Any controls already present on pages show the error 'Object reference not set to an instance of an object'. 

    This occurs on all pages and I am also getting JavaScript errors: overlayUI is undefined for WebResource.axd.

    I have tried replacing my Web.Config file with a known good copy - it is standard other than the appropriate DB Connection String.

    Do you have any ideas what could be wrong?

    Many thanks in advance!

    Hello Steve,

    I think that there is some problem with the .NET version under which the project runs. It looks like the project runes in .NET 3.5, but the application pool is set to use .NET 4.0  or vice versa.

    Best wishes,

    I checked the potential .NET problem IIS 5.1 (Windows XP Professional) and it looks ok, but still experiencing the problem. Is there a fix for it or what?

    Also, it is a bit annoying doing it through the drop-down box when a control already exists in one of the content place holders because the title of the content place holder disappears once it has a control on it.

    Please update!

    Thanks,
    Andrei

    Hi Andrei,

    The only way that we can replicate this issue is in case of the configuration setup mentioned above.

    Kind regards,

    Ivan,

    Due to size restrictions, I have submitted a ticket with a short video demonstrating my set-up.

    Many thanks,
