Thank you for your inquiry.
We are very sorry for the delay.
1) Need steps to follow to get a buy now page(no registration required) up and running.
Currently s2Member requires membership for all checkout styles other than Specific Post/Page. If you need to have checkout available without having your Users sign up, Specific Post/Page Buttons/Pro Forms are for you.
See: Dashboard -› s2Member® -› Authorize.Net® Pro Forms -› Specific Post/Page (Buy Now) Forms
Are you selling access to Posts or Pages, or are you needing to sell access to something different?
2) troubleshooting tips and links if available while doing this work. (ssl, how to test once page is done)
An SSL Certificate is required for Authorize.Net, as you’re accepting credit card information on-site. See the following for information on acquiring an SSL Certificate:
http://www.authorize.net/solutions/merchantsolutions/merchantservices/sslcertificates/
To test your Pro Forms, I would recommend performing 1 cent transactions on your site using one of your credit cards. You can later change the Pro Form that you’re using on your page to up the price once you have your setup working.
Let us know if you have any further questions/concerns. :-)
