I'm running DNN 7.4.2. and for various reasons I would like to change from RADeditor to CKeditor and have a couple of questions:

  1. Will CKeditor open and edit existing HTML module content that was created using RADeditor?
  2. Is the current build of CKeditor vulnerable to the same security issue(s) that the RADeditor was recently patched for?
  3. Can I safely uninstall the RADeditor module / components after installing CKeditor?

The HTML editor in use by DNN will be seamlessly replaced based upon the configured HTML editor. So the HTML-based content you have in any existing module or view will simply use the editor specified in the configuration.

The security issue you're referring to with the telerik controls was very specific to telerik and nothing else. However, that doesn't mean that any other code in any other system won't eventually be affected by a security issue. At this time though, I'm not aware of the CKeditor having any open security issues.

You can successfully uninstall the telerik provider after switching the default provider. However, if any custom/third party extensions are installed that manually use the telerik editor, they will throw an error once you do.

It finally occurred to my empty and shiny head to look at the event log and discovered three errors when I attempted to use the Document Manager in the editor while logged in under the Host account. The summary column of the three is:

AbsoluteURL /DesktopModules/Admin/RadEditorProvider/DialogHandler.aspx Def

AbsoluteURL /DesktopModules/Admin/RadEditorProvider/DialogHandler.aspx Def

AbsoluteURL DefaultDataProvider DotNetNuke.Data.SqlDataProvider DotNetNuke


The information provided via the DNN_vw_EventLog View for the top 2 is:


Object reference not set to an instance of an object.

The inclusion of the GetDirectoryItemWithDNNPermissions gets close to the good tip from K Prouty but that tip didn’t seem to work.
