We have a DNN site and we use the AJAX Toolkit. We upgraded from AJAX 30930 to 40412. We changed the script manager to a ToolkitScriptManager. I have a image button that posts back and calls a modal popup.show() method. When I click the button I get a javscript error before the post back:
Error: Sys.WebForms.PageRequestManagerServerErrorException: This version of MicrosoftAJAX does not offer the ScriptManager.RegisterClientScriptBlock method.
Any suggestions would be helpful. I will obviously provide more detail if needed.
