However to make users pay during registration process is considered as a paid plugin development or modification of the current paid membership plugin and default software. We recommend you to do the first.
You can do that on your own, if you good at PHP, Javscript, HTML and CSS or you can hire a programmer to do that for you. You can do that here: http://www.oxwall.org/market/specialists
Ross, we installed the oxwall paypal plugin for customers to upgrade from Free to Bronze etc, it allows payment to be made from the customer, paypal accepts payment, but the confirmation back to our site is not coming through to our finance page, nor to the customer to allow them to physically upgrade.
Is this because we don't have the 2 plugins you mention above? Or that the IPN url is incorrect? Is the correct IPN url : https://www.mywebsite.com/PayPal_IPN OR https://www.mywebsite.com/billing-paypal/order/notify
[We have put the Merchant ID in the admin of our site] Any help is appreciated, Thank you.
