What does this database error mean.

I got this in my email about 4 of them mailed to me from my website:

Database error in vBulletin 3.8.4:

Invalid SQL:
SHOW COLUMNS FROM user LIKE 'username';

And recently my forums keep going back in forth in time. It's like everything I did disappears (threads, any changes, etc.) and then comes back randomly, but mostly is gone .

And most of my katz traffic is showing up error pages because the threads I submitted yesterday don't exist no more .

It's suppose to show 290 threads and 9 members but it only shows 22 threads and 7 members and it switches back in forth .
