After upgrading Dolibarr from V. 7.0.3 to 8.0.0 it is not possible to add predefined free products (like flyers or gifts for 0,00 EUR) to an order. The error message says “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 ’ , 0, 0, , null, null, NULL, NULL, ‘EUR’, , , , )’ at line 1”
I will have to downgrade to 7.0.3 until this bug is fixed.
Grateful for any ideas or hints how to fix this!!
