I got this error when reading posts after installing de xml

Database error in vBulletin 3.5.4:

Invalid SQL:

SELECT a.*, au.*, post.userid, post.postid 
FROM vb_post AS post
INNER JOIN vb_award_user AS au ON (au.userid=post.userid)
INNER JOIN vb_award AS a ON (a.award_id=au.award_id)
WHERE post.postid IN (0,2789,2790,2799,2808,2820) GROUP BY post.postid

GROUP BY au.issue_id
ORDER BY au.issue_time DESC;

MySQL Error : You have an error in your SQL syntax near 'GROUP BY au.issue_id
ORDER BY au.issue_time DESC

Did all of the template changes, i installed YAAS 2.1.2 On VB 3.4.5

I hope sombody can help me with this error.
The error occures when sombody try's to klik a forumpost.

P.S. I readed al of the post in this tread, its defenitly no Guest post
