Mad SQL problems!

[ZomgStuff]

Well I come home and my co-admin tells me there are SQL errors abroad. DB errors that os.

If I click view PM's I get this

Database error in vBulletin 3.6.5:

Invalid SQL:

			SELECT pm.*, pmtext.*
				, icon.title AS icontitle, icon.iconpath
			FROM pm AS pm
			LEFT JOIN pmtext AS pmtext ON(pmtext.pmtextid = pm.pmtextid)
			LEFT JOIN icon AS icon ON(icon.iconid = pmtext.iconid)
			WHERE pm.userid=1 AND pm.folderid=0
			ORDER BY pmtext.dateline DESC
			LIMIT 0, 50;
