 Upon upgrading to 4.0, on 10 of my WP installs, everything is working
 perfectly.

 However, in 1 of my installs, I can't get anything to show when the Media
 Library ("Dashboard" > "Media") is set to "Grid" mode. Rather, the spinner
 wheel just spins forever.

 It DOES load correctly when I have it set to "List" mode.

 I have WP_DEBUG mode on and no errors are showing. There are also no
 javascript errors showing in the console on Google Chrome.

 Steps I have taken already:
 - I have de-activated all plugins and reverted to the twenty fourteen
 theme
 - I checked the server to make sure there is enough RAM, Hardrive space,
 and other resources.
 - I checked permissions in apache and all are set to be owned by apache
 - I restarted Apache
 - I restarted the entire server (which is a LAMP setup)
 - I have reverted to 3.9.2 and back to 4.0 multiple times (there is no
 "grid" mode in 3.9.2)
