vBulletin Database Errors:

I don't know what the hell all this means, can someone enlighten me?

Database error in vBulletin 3.6.4:

Invalid SQL:

thread.forumid, thread.replycount, thread.lastposter, thread.dateline,
thread.iconid, IF(views<=replycount, replycount+1, views) AS views,
thread.visible, user.username, user.userid, user.usergroupid, IF(displaygroupid=0,
user.usergroupid, displaygroupid) AS displaygroupid
FROM thread AS thread LEFT JOIN user AS user ON (user.username =
thread.lastposter) WHERE NOT ISNULL(thread.threadid) AND
thread.visible!=0 AND thread.forumid NOT IN (0,31,)
ORDER BY lastpost DESC LIMIT 0, 5;

Mmmm....kay..... :confused:

Seems to me your MYSQL server was getting ready to fail on the first error, and on the second error, it had already failed. Try restarting your MYSQL, or rebooting your server... or if you are on Shared Hosting, see if you can log into cpanel, view the status of your services, and if any are failing, report it to your host.

Syntax errors like this are usually caused by custom code. Try uploading the original PHP files for your version. Also try disabling your plugins, especially the last one(s) you ahve installed. Does the problem go away? If so, then you can begin to troubleshoot any custom code that you want to keep.
