Okay, I have vBulletin installed on my website, it's been on there for a month.

And I get this error when clicking the User CP.

Database error in vBulletin 3.7.2:

Invalid SQL:

SELECT pm.*, pmtext.*, userlist_ignore.userid AS ignored
,icon.iconpath, icon.title AS icontitle
FROM pm AS pm
INNER JOIN pmtext AS pmtext ON(pmtext.pmtextid = pm.pmtextid)
LEFT JOIN userlist AS userlist_ignore ON
(userlist_ignore.userid = 1 AND userlist_ignore.relationid = pmtext.fromuserid AND userlist_ignore.type = 'ignore')
LEFT JOIN icon AS icon ON(icon.iconid = pmtext.iconid)
WHERE pm.userid = 1
AND pm.messageread = 0
ORDER BY pmtext.dateline DESC
LIMIT 5;

The User CP's been fine until now.

Any idea?

Make the /tmp directory world-writable and readable i.e. chmod /tmp to 777

Okay,

Will do, I think it got messed up, because my host got hacked and they must have caught the person.
