Clipbucket white page

Hi. I have already installed the clipbucker a few times according to the instructions https://www.vultr.com/docs/install-clipbucket-and-nginx-on-centos-7.
Clipbucket works, but when I want to add a playlist, a white page appears.

Hello,

This sounds like a php version compaitibility issue, follow the official guide and use recommended versions: https://clipbucket.com/docs/installation/
