I have a DNN 9.0.2 site that was upgraded from version 8. The site had one portal and was still using the Rad Editor. I have since created another portal (1) and have the issue of a blank file manager when trying to use the Rad Editor. I have tried to sort this by my going to Site Assets and re-applying folder permissions. This no longer seems to fix the problem.
I found this in the logs and the path looks odd ( /Portals/1//Portals/0 )?
Message:Unable to complete operation. An unknown error occurred. /Portals/1//Portals/0
InnerMessage:Object reference not set to an instance of an object.
at DotNetNuke.Providers.RadEditorProvider.TelerikFileBrowserProvider.GetDirectoryItemWithDNNPermissions(String path) at DotNetNuke.Providers.RadEditorProvider.TelerikFileBrowserProvider.ResolveRootDirectoryAsTree(String path)
The reason I need the Rad Editor to work is because it's still used by a module I'm using in the site. This all works fine in the original portal but not in the new one.
So, looking for any advice on how this could be fixed. Thanks!
