I downloaded the free version and installed it onto one website, which is working perfectly, using joomla 1.5.2 and virtuemart 1.1.5. I've installed again on a site using joomla 1.5.1 and virtuemart 1.1.4, and although I can create a coupon which works, if I wish to view my coupons, it shows a blank white page. Also if I select create a new coupon, but then decide to cancel the instruction, I'm also presented with the same blank page. Please help!!!
