Topic: Error Unable to fetch post info - You have an error in your SQL syntax

Today I keep getting multiple instances where there are 3-4 copies of the same new topic.   When we go in to delete the duplicates we get:

"File: /home/acct/public_html/forum/viewtopic.php
Line: 204

PunBB reported: Unable to fetch post info

Database reported: 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 ') ORDER BY p.id' at line 1 (Errno: 1064)"

Anybody know:

1)  Why we're getting duplicate new topics
2)  Why I'm getting this error when I try to access / delete the new topic?
3)  What I should do?

Thanks so much in advance for any suggestion!
