And if the product page has been changed you need to change it linkname to “products-page” too!!!
Yes! As usual the problem was solved simply
! The page “transaction-page” it shall be published and the mainpage of shop shall be her parent. Don’t delete default pages created e-commerce. sorry for my english, Bros!!
I found it! I hope it will be useful, to someone. In my situation by pressing of the checkout button the e-coom redirected me on hostname/product-page/transaction-results/?sessionid=xxxxxxxxxxx
But we need to replace this on hostname/shop/transaction-results/?sessionid=xxxxxxxxxxx !!! I trying to correct this one in code now.
