We've been upgrading/changing styles once a year, but has 'closed the doors' behind us when we moved forward with new and more compatible styles. Or so we thought! After installing a nifty little Style Statistics add-on, we see that some members are using older styles which they aren't supposed to be using. How is this possible? In Admin CP we have cross-checked only two styles (dark and light version) that are supposed to be visible for the choosing. How then can some of the members use older styles? And better yet; how can we batch change their choice to the default forum style?
