I am unable to go to admin content in (one of my websites using) Drupal 7

What would cause this?

I am unable to access any admin pages in Drupal 7. And this happened after I uploaded all the files from backup and I asked the internet hosting company to do a database restore to a back up a month ago when the web site was working fine.
