Well if you didn't do anything then I would ask your host if they did something. Have you contacted your host?
Your server logs would be a good place to check as well.

You may try restarting your mysql server. ssh #service mysqld restart

That sounds like for some reason the innodb storage engine was removed/disabled from your mysql database. Re-enable/re-add it and restart mysql.

My guess would be the host updated mysql. I have seen this before after host updates.
