Tried editing a member's profile in admin cp to change gender, and although it said the update had been successful, when I went back to look at it, it still said Undisclosed. Just wondering if this was a known issue and if there's been a fix for it.
Humm.. Well, I'm not able to confirm this, when I edit a user and change his sex, it saves for me.
Just to clarify, which version of MyBB are you using?
It works for me in 1.2.1
I don't believe this would be caused by a Browser error as then the browser would have the whole select dropdown screwed up.
