New Glitch After Updating (3.5.7)

[egleiser]

Yikes!
After upgrading my s2member version today (3.5.7), now my PayPal® PDT interferes with all other PayPal transactions on other sites.
When a user does a transaction on s2member everything works fine, but when a user does a transaction on another site, after the payment, it attempts to redirect to my s2member site and throws a crazy error from PayPal that is impossible to copy/paste and would take way to long to write down.

Please help ASAP!
Thanks a million,
E

EDIT:
For some users it throws this error.

EDIT2:
It may have something to do with changing my subdomain and updating it on the PayPal setting page and wordpress. Maybe s2member has issues when a subdomain name is changed. But I still need help

Thanks for reporting this important issue.

Can you please explain in just a bit more detail what was changed and where exactly? This definitely sounds to me like the source of the issue. That error you reported is specifically related to the domain value. Once I see what was changed and where, we can offer you a solution I believe.

Never Mind, I managed to fix it with PayPal Developer Support. It was a bug in PayPal not s2member.
Thank a million though!

Thank you very much for reporting back.
If it's possible, I'd love to hear about the bug that you found, or perhaps a link to another thread where you discussed the issue with PayPal. ~ Thanks!

Well, I talked to PayPal and they did dome unknown behind the scenes stuff and it worked!
Can't say much more than that. The account was having some issues. Some links lead to a PayPal 404/outdated page.

Ah, I see. Thank you again for reporting back on this.
~ much appreciated!
