After having configured our production site according to your guidelines (see viewtopic.php?f=7&t=3867&sid=af67d827890ee622ecb5719f9cb2c3ae#p7962 and private emails), we are now experiencing two problems with VirtueMart, if OPC is active.
Please, note that we had to update VirtueMart due to its payments issues; now VirtueMart is updated to the most recent version. We also updated OPC.
1. Orders doubled
--- Payment method: PayPal or Credit Card
If a customer places an order paying by PayPal or Credit Card, the system generates two identical orders. The status of the first is Confirmed, the status of the other one is Pending. The order number is different, so this makes the customer confused.
--- Payment method: cash or by bank transfer
If a customer places an order paying cash or by bank transfer, the system shows an error message “Cart Empty”. More, only if the customer uses Firefox (not Chrome) the following message appears:
To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.
Cancel Resend
If the customer cancels, the order is sent regularly and the message “Order confirmed” appears.
If the customer resends, the order is sent regularly but the message “Cart Empty” appears.
2. Invoice numbering not resetting
We changed the invoice numbering from nnnn-{05}-YYYY to YYYYMMDD{-05-}nnn, with the reset New Day.
But the actual numbering always follows the previous setting.
Please, can you fix these issues? If needed, we will be glad to pay for your support. We will provide you with a Super User account. You can find the production site here: https://www.latteriadelsole-shoponline.it/.
