a example "Henry's shop" & "untitled product" , you can search these keyword in your client website.
we noticed in database "shop" and "products" - table, Many unwanted products appear here.
Those which will have relation with your dummy data or those products which could not be published or those which have been deleted from the website. These still remain in the database. All these are also visible in search engines. My problem was solved when I cleaned these two tables. Apart from this, the vendor URL was earlier giving 500 server error, it was also resolved.
please solve these issues permanently through a fix update , we mean website strong connectivity with database, If the product is deleted from the website it should also be deleted from the database.
