When I click on a product in Virtuemart it works fine. When I click it a second time the page loses all its formatting (template?) e.g. apart from missing info the blue page goes to white.
I have deleted and replaced menus products categories etc. but still does not work properly.
Update: it seems to be either 2nd click or when I hit the back button it doesn't like it.
I messed around with image sizes and although I think I've put them back to what they were I am wondering if this messed up template/layout etc.
