I am probably doing something really silly, but for some reason, whenever I change the admin account theme, my standard user account theme changes too. Same happens with the standard user account - if I change it, the admin theme changes to match. Change one, the other changes, every time. I have made a custom theme, I have used built in ones, I have used saved ones, unsaved ones, all with the same result.
Here's the really weird part - we have a second standard user account for the kids, and that one stays like it was set. No matter what other accounts' themes are changed, it does not change like the admin and other user account.
Thanks for any help!
