Hi
I just visited your site
prefermarket.com/en/profile/my-store
1. modules are coming, both are listed on the top right column with title. You can't miss these.
Is this solved ?
2. Yes I see , very weird products and tabs disappear, this is due to your template, swtiching to another template solves this, but I'll try to find out what's wrong with it.
Is this only happening sinc you installed the Wishlist component?
If yes, make sure you use the plg_content_vm2wishlist and not plg_vmcustom_vm2wishlists
(of course you will have to enable 'Plugins' option in VM configuration page)
Let me know if this helps
