Add to site settings:
"Show the Upgrade page "Premium" for guests" - Yes / No
Some payment systems want to see the page "Services / Products "
Or any other page with a description of the things that will sell the site.

Guest comes to the home page.
See the link to the "Services / Premium"
On page upgrade.html, he sees the message:
"To purchase Premium, please register"
At this point, guests can not see the page with the purchase of a premium account.
