Some of our users have uncovered a strange bug that prevents them from posting italic text. The interesting thing is it's only affecting them, I can post italic text just fine from my admin account, but I can't from a throwaway default usergroup account.
The text shows up properly in the WYSIWYG editor and retains the tags after posting. It's just the HTML replacement that's not rendering. Every other formatting option works as it should.
Any advice? Am I overlooking a setting or something?
