Images and Featured Images missing


I don't know what happened but all of a sudden I started getting a Fatal Error message on all my posts saying the wp/content exceeded memory limit. I called my hosting and they were able to increase my limit so now my posts are showing up again but there are still issues.

All my Featured Images I had set on all my posts have disappeared and when I go to my media library you cannot see any of my images.....they are all grey squares.

I updated Genesis and changed to a Child Theme and it's still not working.
