Just upgraded to 9.0.1.3 and whenever I try to use the editor to add an image or crate a hyperlink, etc. I get the following error message:
Web.config registration missing!
The Telerik dialogs require a HttpHandler registration in the web.config file. Please, use the control's Smart Tag to add the handler automatically, or see the help for more information: Controls > Editor > Dialogs
If I close that, this:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
