No one touched the db, but all day, everyone on my forum has gotten this db error:

Database error in vBulletin 3.8.4:

Invalid SQL:

SELECT COUNT(post.dateline) AS postcount, post.userid, user.username, usergroupid,
IF(displaygroupid=0, usergroupid, displaygroupid) AS displaygroupid
FROM vb_post AS post
JOIN vb_user AS user ON (post.userid = user.userid)
WHERE dateline > 1272945600
GROUP BY userid
ORDER BY postcount DESC
LIMIT 1;

MySQL server has gone away is an issue you will need to take up with your host.
