I downloaded a wonderful extension that would make it possible to let customers use their coupon code or gift vouchers in the checkout screen. See the extenstion here:
http://www.opencart.com/index.php?route ... on_id=9519
I downloaded it, installed the files in the VQMod folder, and in the module VQMod Manager the extension was marked as enabled. Though, the option is not available in the Module or Payment section of the Admin panel, and neither is the option visible in the checkout screen.
I am quite new in this, is there something I am doing wrong? I would REALLY appreciate it if someone can give me some advice here

Cheers
