In the forum there are some posts about issues around Virtuemart. Since Virtuemart is a Ugly but common component, and I think used by a lot of Joomla51 client, it should be a little sections for suggestions on how operate after this component installation. In my case I am here not to make a child club website, I am here to have Joomla51 as professional platform where choose templates from. I fixed this platform as my template seller. The more clients I have the more buying I will do. I am changing the e-commerce component because VIRTUEMART is ugly. But until make the last decision I would like to highlight the last problem. Can Joomla51 templates have a problem with VM pages rendering? They suggest to point the finger to Joomla51 templates. In the VM FORUM they told that Joomla51 are not fully working with this component: my page is really ugly!! I will try to suggest a product UGLY page below. The template is NINA and I would edit the following php file:

/templates/j51_nina/html/com_virtuemart/sublayouts/products_default.php

Every changes I do there nothing appens.
The link below: the first is a category view; the second is a product view (I would have two columns!).
