original post discussing this bug here:
http://forum.snitz.com/forum/topic.asp?ARCHIVE=true&TOPIC_ID=45639
here is the fix:
pop_moderate.asp
find the following (around line #490): strSql = strSql & ", F_TOPICS = F_TOPICS + 1 "
and replace it with this: if UpdateType = "Topic" then strSql = strSql & ", F_TOPICS = F_TOPICS + 1 "
