Okay, so I've been seeing these really stupid question marks popping up on pages. Usually when you double space or something. So I'd go in and erase the question mark, fixing it, and it would just come back!

Solution: After you erase it, click "Preview" near the "Publish" button, and then when the preview comes up, make sure the question marks are gone, then click the "Publish" button that is on the Preview tab thing that pops up.
