I have this error, when I try to export as CSV or XML :
<?php
user warning: 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 ')' at line 1 query: uc_order_export_form_submit SELECT * FROM dp_uc_orders o WHERE order_id IN () in /includes/database.mysqli.inc on line 151.
?>In fact, I think I should see the order list, and I see "No orders available." Even with no filters applied.
It it can help you...
