I have been struggling from the last 2 days, i have been trying the solutions provided all around the Google but have tough time in fixing the issue.
I am using ToolkitScriptManager and ModalPopupExtender in my Login Page but when the Login Page is loaded i get 3 Javascript errors and it makes ModalPopupExtender useless.
The errors are:
ASP.NET Ajax client-side framework failed to load.
'Sys' is undefined
'Sys' is undefined
This works fine in my local machine and Production but in Development Server, I have this problem. Please help.
Comments: Use the F12 in IE (or similar). Usually "Sys undefined" means the .axd scripts are not loading for whatever reason (like a 404 file not found, etc).
