Hi,
As far as I can see this feature has been removed since versions 2.x.x. Is it possible add in next versions again?
Thanks.
If you restored whole web site including DB, unfortunately it seems that your content and images were erased. But if you only restored the files and do not touch DB, your content are still there..
Best option, you may contact to your hosting provider to restore latest backup. After this, you can start to update again.
