SQL error in znote after turning on achievements

[Verrine]

Hi. Im troubling with mysql error after I turned on achievments.
When I click on character profile page it shows up:

string(101) "SELECT SUM(`value`) AS `sum` FROM `player_storage` WHERE `key` LIKE '30___' AND `player_id`=(int)1715"
(query - SQL error)
Type: select_single (select single row from database)

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 'int)1715' at line 1

Whats wrong?
