WordPress database error

Im getting strange error in Ultimate Product Catalogue
when I click on categories under Ultimate Product Catalogue
I get this error:
WordPress database 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 ‘BY Category_Sidebar_Order, Category_Name LIMIT 0,200’ at line 1]
SELECT * FROM wpss_UPCP_Custom_Fields ORDER BY Field_Sidebar_OrderORDER BY Category_Sidebar_Order, Category_Name LIMIT 0,200
