rayramonr on "[Plugin: UpdraftPlus Backup and Restoration] Fatal Error: Can't access admin area"

I've got a Fatal error: Call to a member function get() on a non-object in /home4/instcert/public_html/MYSITEINFO/wp-includes/query.php on line 28

I can't access the admin area, is there a way to restore my site from backups without being able to access the admin area?

Thank you.
