Hello and thank you for this module.
I have been using and it works well, but recently I have issues when I try to modify stocks in my backoffice. I have this message:
You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'AND id_country = 74 AND vat_number = ''' at line 3
SELECT * FROM ps_vatchecker WHERE id_address = AND id_country = 74 AND vat_number = ''
I have to dissable the module to modify stocks or prices and then enable the module again.
Please let me know if there is a solution to this problem.
