One-Page Checkout [Support Thread]

[lat9]

OPC 2.2.2, Zen Cart 1.5.6c.
Entering a coupon code on the checkout_one screen causes the success message to be shown twice. See image.
Seems to happen on all templates (here shown on responsive_classic).

Yep, I've noticed that too. I'll see what I can do to correct in the forthcoming v2.3.0 release.
