Good morning! I do not understand how to make the seller's page..in the global configuration I already have enabled marketplace option; I created a menù voice with a seller's page, but I don't find where select the seller that will be displayed on that page! So when someone enters in that page, it displays this error: "There was no store selected or the selected store was not found. Showing products from all stores." How Can I resolve this? Sorry for my bad english
