Simple Specific page access

Trying to simply sell access to a specific page without the buyer becoming a member. I enter the page id in the Specific Post/Page Access Restrictions (optional) section but the set up keeps redirecting to the Membership Options Page.
Is there specific detailed documentation on setting up this process?
Would appreciate the help.

Is this page also protected by a level or ccap? If so, that won’t work.

You need to treat pages with specific access as entirely independent of any pages protected in the usual way by s2Member.

There is no way for s2M (and any other content protecting plugin) to work, if the user is not a member. Like, me to go to the bank, to ask money from your bank account and to not need ID/license/identification…
