If you restore a site using cPanel or JetBackup and get the 403 Access Denied error there is a chance that the group ownership is set incorrectly. Ownership of the public_html files needs to be accountusername:nobody and not accountusername:accountusername.
To fix the group permissions, run the following command:
chown -v username:nobody /home/username/public_html
- On a mounted volume: chown -v overhaulics:nobody /mnt/home2/overhaulics/public_html
