I updated Drupal 7 over the past few releases and today went in to look at my content listing. Unfortunately, Drupal 7 greeted me with a blank white page. I saw that on a couple other pages as well though the configuration pages still work OK.
Is this a known problem? Any suggestions?

Also, thinking about going to Drupal 8, but is this basically a re-install and start over given the steps involved?
I'm exploring the idea to use MongoDB for drupal installation, but I want to use MongoDB to store only files and use normal Mysql/MariaDB to store other informations.
The question is: Is it possible to use MongoDB instead of sites/default/files (directory)?
