This made me say "OK now what the f*#%?"
I don't know of this applies to anyone else, but I got this when I visited the following link:
Notice: Undefined index: raw in
eval()'d code on line 19 Question2Answer query failed:
SELECT DISTINCT postid FROM qaedithistory WHERE postid IN
(98317,,100159,100161,100863,101017,101134) GROUP BY postid
Error 1064: You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to
use near '100159,100161,100863,101017,101134) GROUP BY postid' at line
And I'm not sure what you can do about it, if anything at all.
