Har virkelig brug for hjælpe med denne MYSQL-fejl

Hej

Jeg har netop installeret mit script hos en host og så får jeg denne meddelelse:


A Mysql error has occurred while running the script:

The query you are trying to run is invalid
Mysql Error Output: 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 ') OR a.addl_category_id IN ())' at line 2
SQL Query: SELECT count(*) AS count_rows FROM probid_auctions a WHERE a.active=1 AND a.approved=1 AND a.closed=0 AND a.deleted=0 AND a.list_in!='store' AND a.catfeat='1' AND (a.category_id IN () OR a.addl_category_id IN ())


Scriptet virkede fint på min local XAMPP

Hvad kan det være og i så fald hvad skal ændres?
