SYSK 240: AJAX.NET – Resolution for Sys.ScriptLoadFailedException when Opening Login page

Are you getting Microsoft JScript runtime error: Sys.ScriptLoadFailedException:

The script '/YourSiteName/ScriptResource.axd?d=ebUIu-RsatQBXvExgP5y3pvOqX2PbIJ6uav4Avk4QzmounX74siwLINKKPmlFz54oTPVrGJa4XpgCYiosTExfEdJoHleHTQaH7TE19A6Hqg1&t=632986009464531250' could not be loaded or does not contain the Sys.Application.notifyScriptLoaded() callback

 

Is your authentication mode = “Forms”? Does it happen when you’re loading your login page?

 

To resolve the problem, add:

<location path="ScriptResource.axd">

            <system.web>

                  <authorization>

                        <allow users="*"/>

                  </authorization>

            </system.web>

      </location>

 

to your web.config.

  Sounds like you're missing things in web.config.  Consider creating a new AJAX project, and compare your web.config with that one.  Also, if you only get this in design view, just ignore it...  it's a known problem when using master page.

  Sounds like something is missing in web.config.  Did you 'Ajaxify' an older asp.net project?  Try creating a brand new ASP.NET AJAX-Enable Web Site, add an update panel and see if you get any errors...
