Blank Site on Restore

I used WP-Clone on a website and restored it to my WAMP server successfully. I then made some changes and made a new back up and imported it into the live server. I clicked refresh and the website would not load at all. It was all white and in the dev console, there was an error 500. I managed to re-install wordpress and wp-clone and then restore my original version and the website was finally visible again, HOWEVER, wp-admin now get’s the white screen and I can no longer access the page.

Note, the files are actually all there. So it is probably some sort of permissions or access thing that can be changed, but I do not know what that would be.

Anyone have this issue?
