I have a Wordpress site with a Memberpress membership plugin. When a user creates an account and becomes a member of my program, they are supposed to go to the paypal payment screen to complete the transaction. This was working fine for testing with the Sandbox API credentials. After I changed it over to using Live NVP/SOAP API credientials it is not working. Now, after creating a new account, I do not get taken to the Paypal login site to pay for the membership. That entire part of the process doesn't happen. Users are able to just log into my content without paying.
