Hi, Our WordPress site uses a plugin called Ultimate Membership Pro that was accepting payments through PayPal for a year, but then it stopped for unknown reasons. The plugin is still activated and functioning aside from processing PayPal. The malfunction did not coincide with changes to the site hosting or SSL certificate. I tried setting "Block Non-encrypted Website Payment" to OFF since that seems to be a common solution to this problem. I have tried the original PayPal account as well as a Sandbox account with the plugin in Sandbox mode. I tried generating an uploading a public certificate to the PayPal account. I tried entering the merchant ID to the plugin There is no apparent problem with access to IPN file which can be accessed manually via URL other than the fact that it doesn't contain any meaningful information. ============= Ultimate Membership Pro - PAYPAL IPN ============= No Payments details sent. Come later Here is a decoded error URL without the %hex characters. The forum made me remove the email address before posting and I had to add a spaces to the addresses to prevent them from being obscured: www.paypal. com/cgi-bin/webscr?cmd=_xclick-subscriptions&business=emailatemail.com&item_name=member¤cy_code=USD&a3=20&t3=Y&p3=1&src=1&srt=0&no_note=1&modify=1&lc=en_US&return=https://www.hawaiistateruralhealth.org/iump-account-page/&cancel_return=https://www.hawaiistateruralhealth .org/iump-account-page/notify_url=https://www.hawaiistateruralhealth .org/?ihc_action=paypal&rm=2&no_shipping=1&custom={"user_id":"114","level_id":"5"}&Z3JncnB0= or encoded www.paypal. com/cgi-bin/webscr?cmd=_xclick-subscriptions&business=emailr%40email.com&item_name=member¤cy_code=USD&a3=20&t3=Y&p3=1&src=1&srt=0&no_note=1&modify=1&lc=US&return=https%3A%2F%2Fwww.hawaiistateruralhealth. org%2Fiump-account-page%2F&cancel_return=https%3A%2F%2Fwww.hawaiistateruralhealth. org%2Fiump-account-page%2Fnotify_url=https%3A%2F%2Fwww.hawaiistateruralhealth. org%2F%3Fihc_action%3Dpaypal&rm=2&no_shipping=1&custom=%7B%22user_id%22:%22116%22,%22level_id%22:%225%22%7D&Z3JncnB0= Any help would be greatly appreciated.
