    We had to move a website to a new server. We went from win2k iis 6 to win2k8 iis 7. Now, whenever I use the rad uploader I get a popup with this error.

    Rad Upload Ajax callback error. Source url was not found:


    Did you register the RadUploadProgressHandler in the web.config?

    Please, see the help for more details: RadUpload for ASP.NET Ajax - 
    Configuration - RadUploadProgressHandler

    I saw this post http://www.telerik.com/community/forums/aspnet-ajax/upload/radupload-ajax-callback-error-source-url-returned-error-500.aspx and did what it had said but it didn't fix my problem. I have attached my web.config

    Hi Web Services,

    It seems that your web.config didn't paste. Could you please try pasting the relevant parts of it again so that we can take a look at it.

    When migrating to IIS7.0+ you need to register the RadUploadHttpModule and handler inside the system.webServer tag. Instructions on how to do it can be found here. The easiest way is to use the RadProgressManager smart tag to register them for you.

    Sincerely yours,

    Thanks, that fixed it. I can't do that because this site is deployed on a newer machine that it is developed on.
