I'm having issues with the file upload & Image upload (In the htmlEditorExtender). I'm using .Net 4.5 and the latest AjaxControlTools (7.1005 - Sept 2013.) - IIS 6
Apparently I need to a add the following to the web.config file:
<add verb="*" path="AjaxFileUploadHandler.axd" type="AjaxControlToolkit.AjaxFileUploadHandler, AjaxControlToolkit"/>
But when I do, the entire site breaks and I get the following error:
500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed.
I appreciate any help.
