Two errors on sitemap 2.6 b2

Code:

Database error in vBulletin 4.0.3:
Invalid SQL:
        		SELECT ap.*,p.caption
        		FROM vb_albumpicture ap
        		LEFT JOIN vb_picture p on p.pictureid=ap.pictureid
        		WHERE state = 'visible' AND albumid = '2728';
MySQL Error   : Table 'xx.vb_albumpicture' doesn't exist


Database error in vBulletin 4.0.3:
Invalid SQL:
      		SELECT 
      			count(*) as maxre
      		FROM vb_tagthread
      		GROUP BY tagid
      		ORDER BY maxre DESC
      		LIMIT 0,1;
MySQL Error   : Table 'xx.vb_tagthread' doesn't exist

It runs after I turn off inclusion of user albums and tag pages respectively.
