Hello, good evening everyone. I want to add a product to my website, but when I input the product, something like "?v=ebe021079e5a" appears at the end of the link. For instance: https://domain.com/?v=ebe021079e5a Originally, it used to open like this: https://domain.com/ I think I made a mistake somewhere. I can't find a solution. Are there any friends who understand the issue?
