Status Error and blank status page
I just fixed this issue on a site I was working on.  Hopefully it helps you as well.  My issue was directory permissions.  You need to make sure that all of your directories have permissions set to 755.  My contribute folder was set to 750, which did not allow the directory structure to be loaded beyond that point.  Because of that, it's not able to load the angular-modules.2513685c7e9bf04c4c187f640cffc720.js file.

An easy way to do this is to use FileZilla and navigate to somewhere you know is ok, maybe your /var/www/html/drupal/sites/default/ directory.  Then you can right-click on the files folder and choose File Attributes or File Permissions depending on which pane you use, and make sure permissions are set to 755.  Now choose Recurese into subdirectories and MAKE SURE you select Apply to directories only, you don't want to apply it to files.  Click OK and once it completes, try going to your system status page again and hopefully it works now!
