What a nightmare!

Hope the below helps:

1) Change the usernames and password for all related logins – wp-admin, cPanel, FTP, hosting account, email, domain regsitry – everything! That should stop the ex-admin from screwing things up again.

2) Have a look at

It’s from Oct 2016 but may help if you can’t get your content back any other way.

3) It’s a long shot, but see if there are any old page revisions that can be restored.

4) Log in to mySQL and have a look through the tables for the content. Again, the ex-admin has probably made a decent job of wiping everything but it’s worth a look.

5) Speak to your hosts again because most decent hosts have some sort of backup they keep for a certain time. There may be a cost but it will probably be worth it.

I note that the theme has also been reset so he may have just done a complete re-install, in which case your hosts are your best bet.

Hope this helps in some little way, and good luck ??
