F.Y.I. CC and Mods

I found an easy way to disable any custom content and mods before uploading to the gallery. Un-check the CC and mods in options.
Reload the game, then load the household (or character), the lot, or room you want to upload. Then save to library and post on gallery from library.

This also works if you think a mod or CC is causing a problem in the game. You don't have to go into the Mods folder and delete everything.
(Of course if it is a mod or CC causing a problem, figuring out what it is a bit more tricky)

P.S. The 'Script mods allowed' won't be enabled if CC and mods are disabled anyways.
