Hmm you done Backup to Server, if you want to load saved settings you should go to Restore from Server.
I don't really understand what is the problem here, so feel free to explain it little more.
Oh! It just worked for me!
I thought the backup wasn't carried out because after clicking the "Backup" button, I was expecting to read the current date and time instead of "not available" next to "The last backup from this browser:".
I had never even tried to restore because I thought it hadn't backed up.
Perhaps it could help to make it clearer what's going on behind the scenes!
