I’ve just upgraded Magento from 220.127.116.11 to the latest version (18.104.22.168) and I have this error when trying to place an order from frontend.
It’s about my orders’increment ids. I shall have a new order increment id according to the eav_entity_store table it should be :
But it proposes me M03454 when I try to reserve a new order increment id. This id is corresponding to the last order from the same customer.
If I use another customer account, I have another increment id, still the last of this other customer.
I don’t understand what’s happening, does someone already had this error ?
Edit : When I try to order with a new account : no problem, if I try to make another order with this new account, still no problem, so problem seems to exist only for old account.
