I created a Paypal subcription button. Set payment in sandbox test. I enable IPN it paypal test account and configure Simple Membership plugin follow your document. But I got this message “The link you have used to enter the PayPal system is invalid. Please review the link and try again.” when click on Subscription button. I tried using live account with live mode but still get this message.
This is button form
<form method=”post” action=”https://www.sandbox.paypal.com/cgi-bin/webscr”><input type=”hidden” value=”_xclick-subscriptions” name=”cmd”><input type=”hidden” value=”utf-8″ name=”charset”><input type=”hidden” value=”TipsandTricks_SP” name=”bn”><input type=”hidden” value=”sample@inbusiness.no” name=”business”><input type=”hidden” value=”NOK” name=”currency_code”><input type=”hidden” value=”3332″ name=”item_number”><input type=”hidden” value=”5 Years Membership” name=”item_name”><input type=”hidden” value=”1″ name=”a3″><input type=”hidden” value=”1″ name=”p3″><input type=”hidden” value=”D” name=”t3″><input type=”hidden” value=”1″ name=”sra”><input type=”hidden” value=”1″ name=”src”><input type=”hidden” value=”60″ name=”srt”><input type=”hidden” value=”1″ name=”no_shipping”><input type=”hidden” value=”http://unisonelektro.inbusinessclients.no/?swpm_process_ipn=1&#8243; name=”notify_url”><input type=”hidden” value=”http://unisonelektro.inbusinessclients.no/membership-login/&#8221; name=”return”><input type=”hidden” value=”http://unisonelektro.inbusinessclients.no&#8221; name=”cancel_return”><input type=”hidden” value=”subsc_ref=2&user_ip=115.79.62.159″ name=”custom”><input type=”submit” value=”5 Years subscription” class=”swpm-subscription-button-submit”></form>`

It works if I use ‘Paypal Buy Now’ button type.
Please help me to fix it.
Thanks in advance.

Hi, did you set up your PayPal IPN correctly? When you tested live did you disable the Sandbox testing option? Can you enable debug mode and check the log file?

Thank you

I fixed my problem. The billing circle should not be greater than 30. I think you should notice it in your plugin. I spent much time to find out the cause of problem. Thanks for your answer.

Hi thank you for reporting back. How did you come up with your solution? How many days did you originally have in the billing cycle?

I tried to create subscription button in paypal and put its form to my page and it works, so I see that paypal limits the number of billing circle at 30 circles or never stop recurring until user stop it manually via their paypal. Then, I tried to changes Billing Circles in your plugin to 30 instead of 60, it works after that. I would like to create a subscription for 5 or 10 years and my customer pays every months. So the circles is 60 or 120. But Paypal standard payment doesn’t support. I heard that I can use express checkout as a solution, but your plugin doesn’t support express checkout. 🙁

yes, unfortunately we only have the PayPal standard subscription at the moment.
