We are sorry, no payment method matches the characteristics of your order. Please .

Hi,

We are having trouble with coupon codes offering 100% off whatever is in the cart. When customers use a free checkout coupon, they receive the following message and are unable to check out:

We can provide further information but would rather not provide it publicly.

Current website stats.  Joomla 3.9.13, Virtuemart 3.6.8 10197, and AWO Coupon 3.5.7.2

Hello,

This bug crept up in 3.6.8.  Even with AwoCoupon uninstalled it is buggy.  You can enter a 100% coupon but the payment method does not update until you do a page refresh.

In any case, I assume you have a payment method to handle 0 value orders.  Please install the latest 3.5.7.3, then go to admin > awocoupon > awocoupon > installation check, and make sure file update for vmpsplugin.php is installed.  It should work normally after that.
