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.
