I'm running Joomla 2.5.27 and VirtueMart 2.6.12.2. I am also using Offline Credit Card Plugin.
This only happens with Offline Credit Card Plugin. When I make a purchase, both the shop owner and customer get duplicate emails. I've re-purchased the Offline Credit Card Plugin and installed the latest version but still happening.
Any ideas?
I've seen other posts, but they all recommend hacking the core and i don't want to do that.
