I tried to upgrade to 3.4.2 but my server don't support MySQL 5.5.31. So in order to have my site up and running I decided to restore from a backup created just before the upgrade. The site is up and running but when I try to go to site admin the link doesn't work at all.
I tried to get through /admin/index.php but it gets me Exception - Class 'admin_setting_agedigitalconsentmap' not found
What is happening???
