Reintegration of the Ultimate Membership Pro plugin with PayPal

Hello, I’m using Ultimate Membership Pro - I have configurated PayPal and it worked well but right now when I’m trying to pay via PayPal there is an error “Things don’t appear to be working at the moment. Please try again later.” Can you give me information about what is wrong? My IT company checked server configuration, apache logs but it seems like there is a problem with PayPal API and Ultimate Membership Pro plugin. Maybe there is a conflict with other plugins but maybe you have more documentation and knowledge about Membership Pro and maybe there is a quick resolve of this problem. I’d be very grateful for your help. Now the payments on my website are blocked. Best regards! Max Bojarski

I am having the same problem. I have checked all PayPal credentials and nothing is working.

Did you ever figure it out I’m having the same problem
