Stripe submission never posting

When I try to process a new member with a credit card for Stripe with the pro version set up, it never gets past the signup page. When I click submit nothing happens.

Here’s a test page I created:
http://tradejolt.com/wordpress/index.php/aaaa-test/

I created a test form to try this out here: Warning: it may bill you the $10 if it succeeds!
So I suggest using a bogus card. Any response - even an invalid one - would be welcome.

I’ve examined the log files s2-http-api-debug.log, but I’m not sure this is where I should be looking.

It’s seems the submitted form is not receiving or processing some callback function.
Maybe its a stripe error, but where can I see those error values? I’ve been stuck on this for
several days now.

I hope someone else has run into this - and solved the problem.
Thanks
Serge

No responses from anyone yet, but I’ve done more digging. It may be that I was looking in wrong log file. I went to my apache log and found:

[Wed Jun 02 21:39:09.687173 2021] [:error] [pid 3072:tid 46971840034560] [client 184.88.202.181:54814] 2021-06-02 21:39:09.675 [34460] 1loYZx-0008xo-LJ 1loYZx-0008xo-LJ no recipients found in headers, referer: https://tradejolt.com/wordpress/wp-admin/admin.php?page=ws-plugin--s2member-trk-ops

Could this be my problem? If so how do I add correct headers? Any input would be appreciated.
