Error of MySQL
 

i installed VB AD MANAGEMENT yesterday, and it goes right. Today I insert a table into left ad column, but after it. The fourm couldn't be show correctly with the error reminder as below:


Database error in vBulletin 3.8.1:

Invalid SQL:

SELECT threadid, title, dateline, lastpost, visible, open, postusername, postuserid
FROM thread AS thread
WHERE NOT ISNULL(threadid) AND forumid IN () AND visible = '1' AND open!='10'
ORDER BY dateline DESC

LIMIT 0, 5;

So, how to resolve this problem?
1. How to do after selecting threadid, title, dateline, lastpost, visible, open, postusername, postuserid FROM thread? Does all these should be limited 0 - 5? I think not, for title written 250 original, how could it be shortened in 0-5?
2. What does this mean "WHERE NOT ISNULL(threadid)", Now it is threadid >> INT >> 10 >> NOT NULL, should I change it into "NULL"?
3. Does "forumid IN () AND visible = '1' " mean I should type 1 in the row of visible [smallint(6)] in forumid?
4. Does "open!='10' mean I should type 10 in Open>> smallint >> 10(Original is 6)?
5. What does this mean "ORDER BY dateline DESC"?

and, anyother thing I should change?

Disable your plugins and see if the error goes away.
Note: To temporarily disable the plugin system, edit config.php and add this line right under <?php

If you want to know what all the mysql terms mean, then you should go take a look at the mysql site. Do a search of "mysql term" - example:
"mysql limit" - http://php.about.com/od/mysqlcommands/g/Limit_sql.htm
"mysql null" - http://dev.mysql.com/doc/refman/5.0/...with-null.html

etc.

Thank you so much. after i close the "Recent Thread function" of "Sidebar Column plugin", all resovled.
