Fatal error after enabling backup and migrate module I just enabled back up and migrate module. Then I backed up my site and tried to restore the site using the back up file and it did not allow me to do it. 

Then when I go to admin > config > I get this error:

"One or more problems were detected with your Drupal installation. Check the status report for more information."

Then I go to admin > reports > status reports > click run cron manually > I get this error:

"
