I got an Internal Server Error. At that point I tried to restore a snapshot backup and wasn't able to do that because of some 'unmodifiable' files on the server due to permissions. I asked the host about this and was told I should create a subdirectory and restore the backup to that. So I tried that and then moved the restored backup to the root directory but the Internal Server Error was still there.
Then I left it up to the host to try to restore the site and they brought it back and suggested it was a plugin issue so deactivated the plugins and reactivated them one by one. The site is now working but there are some issues and I think it's connected to the file structure being set up for the subdirectory rather than the root.
I also tried once again to restore a snapshot backup hoping this would resolve the issues but I am getting an error message:
ERROR: The Snapshot file not found: /snapshot-XXXXXXX.zip
ERROR: The Snapshot file not found: /mysite/subdirectory/wp-content/uploads/snapshots/snapshot-XXXXXXX.zip
