Isaac I read your answer right you say
If a member has chosen a style, then that style is later disabled or deleted, the member's style gets reverted to forum default.
Feedback I have not deleted the styles only disabled a few days ago and now after I changed the active UBBT77 to UBBT77Dark I tested one members account and it still showed his old chosen style.
Maybe I need to delete the style before it changes to default.
Just for you to know.
Cheers
