Close. You need to delete all the files in retail\WTF\Account folder (do not delete any folders). The files will recreate upon your next login. Then, in the same Account folder, go into your server folder (mine says “Stormscale”) and you’ll see a folder for each character you had. Delete all the files in those folders too. Restart your game, log in, delete any old templates you had created in Edit Mode, and should be fixed. The idea is you purge all old material.
