I upgraded to 2.3.3 and now the theme I am using (a modded 130106 1.0 by Isnaini)keeps resetting itself back to Kubrick. I set it back and a few hours later I return to find it back to Kubrick. All was well before I upgraded. I have even changed the admin password in thinking that someone may have been playing games. I am at a loss as to why this happens. I have reset it back to the proper themes about 4 or 5 times and sometime over the next few hours it goes back to the default.
