the first recover mistake made was trying to upgrade a non functional forum from 220.127.116.11 to 7.6.2
If you have nothing as far as a backup of your files. You may try to contact your host and see if they can restore the folders.
They do make backups on some time basis. just for their use and they may offer a solution to reload the folders.
Some of the important folders is as gizmo stated
If the host can't help you, you may also try to do a fresh install in the same folder but use a net new database just for the install..
Make a backup of the site files first
Then I would just watch the ftp program and overwrite everything from the zip file in the members area ver 18.104.22.168.
Then just edit includes/config.inc.php with the old original good database connection info.
Then you can go over the complete cp and manually add back all of your missing items that you can.
