Database Error – Unknown storage engine 'InnoDB'

You seem to have moved your site to a MySQL server that does not support InnoDB — check with your host to see if it can be enabled. If not, you’ll have to change those tables to use MyISAM instead of InnoDB.

Thank you. I made no such changes. Perhaps HostGator moved me to a different server?!?

On the line with HostGator. They say one server there was compromised. Down about an hour and a half. About another hour or so to fix. They said only sites using InnoDB were affected. They said this is a new vulnerability just discovered and they are working to resolve it. They say all sites affected will receive a notice once repairs are completed.

Good Afternoon,

We’d like to start by apologizing to @leadtradio for the trouble yesterday with the MySQL service on this server, but are happy to report the issue has now been resolved. That said, we wanted to jump in here to clarify that there this was not actually a compromise of the server and instead, found that the MySQL service required emergency maintenance as disclosed on our forum here : https://forums.hostgator.com/06-01-2016-14-30-gator4077-t342596.html?t=342596&highlight=gator4077.hostgator.com
