I have set up a WordPress site with MemberPress and integrated PayPal following the exact steps outlined in your documentation: PayPal Standard Integration. Despite the correct configuration, I am encountering the following error message from PayPal during transactions: “Unfortunately, a system error has occurred. Please try again later.” Memberpress support told me: "If what you see in MemberPress -> Settings -> Payments tab, PayPal section, matches what you see in your account in https://www.paypal.com/businessprofile/mytools/apiaccess/firstparty/signature page, and all other settings in https://www.paypal.com/businessmanage/preferences/website and https://www.paypal.com/cgi-bin/customerprofileweb?cmd=_profile-ipn-notify are as we discussed before, then it would be time to contact PayPal support and ask them to see what's going on." Here are the steps I have already verified and completed: •API credentials have been correctly entered in the settings. •IPN (Instant Payment Notification) is properly enabled. I would greatly appreciate your assistance in identifying the cause of this issue. Are there any additional settings I should check, or are there known issues with the current versions of MemberPress or PayPal? Thank you in advance for your support. Best regards, Patrick
