Contact the seller for the product

Hello I am inexperienced with VM
I use VP with the VMVendor components as a catalog of Jomsocial members.
How can I add the contact to the seller to the product?
At the moment you can only see the product and the review in the Frondenbd but not who the seller is
Thanks for the help

Hello You need to enable Joomla plugin in Virtuemart configuration
and then make sure the Joomla plugin called plg_content_vmvendor to be enabled.

Hope it helps.

Thanks for the answer.
all plugins are activated - but it doesn't work.
1. Only "obsolete views / layouts" work in the product overview. (Frontend link category overview All products ")
2. I have no contact details for the seller of the product.
I would like to use VP as a catalog that JS users (Empresas / Companies / Companies group) can publish their products.

Can I save you access data for the backend?

What do I have to do, the contact details for the product (Jomsocial) of the seller are visible?
