No upload button, infinite loading animation on the screen

I have kind of a unique situation, I have a VPS that I installed Centos Web Panel on, this is on Centos 7, and installed OwnCloud through the web installer, owncloud loads, but it does not load the files page, just has the spinning circle in the middle of the page, and no upload button appears, I have tried to make sure that everything owned by the CWP user and permission set correctly. I tried everything I could find but still no luck.

This is the most recent version of owncloud, and everything else like the Marketplace seems to load fine.

Could you provide some information on how exactly did you install owncloud?

Do you have access to command line? Can you look in the log file?
