I had a user who couldn't see a few pages / lists even though she had full rights to read and contribute. The page would be blank (no error) if she tried loading them. In order to fix this, I had to add her to the site collection administrators, then immediately remove her, meaning none of her permissions actually changed. She can now load the pages and see the lists.
I guess I'm just wondering if anybody has had this problem? Is it a known bug? This could be happening to other users (no reports of it yet) and I just want to be proactive about it.. Thanks
