Plugin is installed on a MU network site, but there is only one site thus far. I have set up a single membership level. When calling the Regisster page and entering and submitting registration data, the screen resets/redisplays but does not advance to the payment page. The user is correctly added to the Users file however, and the welcome email goes out via Automessage.
What can I do to get Register to correctly call and display the payment page?
Of note, the site is running over https:// exclusively.
