Migrated through CPanel

A couple days ago I migrated this same site to a different as a “Backup” and it did flawlessly, now I’m trying to do it again to finally set it in place but for some reason wordpress now shows “There has been a critical error” tried again and same result.

I have been using your plug-in for quite a while and this is the first time this has happened. How do I fix it?
