MyBB Community Forums - MyBB SQL Error on forums.kaizokuden.net

The error comes when I tried to visit the "Contests!" section. However, all sub forums work fine.

MyBB has experienced an internal SQL error and cannot continue.

SQL 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 ',,,,,,,,,,,,,,,,,,) AND (visible='1' OR visible='0')' at line 1
Query:
SELECT tid,uid FROM mybb_posts WHERE uid='773' AND tid IN (,,,,,,,,,,,,,,,,,,,) AND (visible='1' OR visible='0')

What do I need to do to fix this?
