i cant say if it will work for u guys as well but when i changed all the post in video format to standard my pages started to show instead of showing blank. i figured that out when one of my catagories where all my videos were not showing, and all my other pages were working. but when added a video format in one of the other pages they also came up blank, so i removed the video format post and it started working again. hope this will help you guys.
