"Database Error"

[Supersonic]

I get one of these whenever I view a thread with a hidden link, unless I have logged out first. Can someone help diagnose my problem?

It would help if you copy and paste the error here.

Screenshots please.

Okay, now I can't view any posts unless I'm on a different account. Something is seriously wonky with my account.

Relevant info on the error page:

<!--
Database error in vBulletin 3.6.2:

Invalid SQL:

REPLACE INTO threadread
(threadid, userid, readtime)
VALUES
(3128, 60, 1177547904);

A screenshot is unncessary because the error page is completely nondescript. I will however confirm that it is server-generated.

I had a problem with this the other day on some threads, but it's gone now.

I'm getting this exact same problem with one of the threads in the Pictures forum- all other threads seem to work just fine except for this one (http://www.fuckingcoolshit.com/showthread.php?t=2968)

Earlier today if I was logged in I couldn't open any forums or view any threads. If I logged out everything worked fine. I tried creating a second account, had the same problems.

Everything seems to be working fine now.
