template problem in Virtuemart categories and products

Hi,
I installed the template on a fresh Joomla 3.8 website where I imported my products
When I click on menus to VM categories, the template is not displayed
In VM configuration, Storefront template is set by default for shop and categories
Could you have a glance at the web site here ?

thanks

I think that's may be due to the fact I installed the template after the joomla install (classic intallation)
I should have used the quick-start in one single installation (Joomla + template)
I'm going test this option.
