I have a FRESH 9.2 DNN CE installation on a testing environment and had to delete my customized theme and instead of pointing to the default skin of the 9.2  installation  Xcillion   it pointed to a non existent and obsolete skin from version 7.x  with the following message

Could Not Load Theme: /Portals/_default//Portals/_default/Skins/Gravity/3-Col.ascx, Error: The file '/Portals/_default/Portals/_default/Skins/Gravity/3-Col.ascx' does not exist

I tried clearing the cache and restarting the application but the error did not go away,  the only way it went away is to set the individual page to a specific skin and then revert it back to the default skin.

Using notepad ++ i found reference to the gravity skin in the following files:

C:\inetpub\MyWebsite\DesktopModules\Admin\Dnn.PersonaBar\Modules\Dnn.Prompt\App_LocalResources\Prompt.resx

C:\inetpub\MyWebsite\Portals\_default\Default Website.template.en-US.resx

C:\inetpub\MyWebsite\Providers\DataProviders\SqlDataProvider\07.00.00.SqlDataProvider

C:\inetpub\MyWebsite\Providers\DataProviders\SqlDataProvider\07.00.01.SqlDataProvider

C:\inetpub\MyWebsite\Providers\DataProviders\SqlDataProvider\07.02.02.SqlDataProvider

Is there way to set the fallback skin/theme to the default skin of the DNN installation (Xcillion)  or any other skin of choice?

I agree the issue can be resolved and was resolved but why in the first place the reference of an obsolete theme from ver 7.x  (and not part of the refresh installation of 9.2 ver) is still present in the code as a fallback skin.....
