Hi I install the mobile detection and style product but now on mobile phones it says database error.
The complete error is
Database error in vBulletin 3.8.5:

Invalid SQL:

SELECT *
FROM style
WHERE (styleid = AND userselect = 1)
OR styleid = 2
ORDER BY styleid ASC
LIMIT 1;

MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'AND userselect = 1)
OR styleid = 2
ORDER BY styleid ASC
LIMIT 1' at line 3
Error Number : 1064
what can I do?
