X-payments problem after server change
We migrated to a new server with PHP 7.3 and other updates.
Whenever we try to process an order, we get 'Error: The card information entered is not valid. Please check and try again.'
This is happening on version 3.1.4 and 3.1.5.
It looks like the Luhn calculation is failing every time even with valid card numbers?
Do you have any suggestions as to what server settings we might look to to determine why this problem occurs?
X-Cart version 4.7.11
