I disabled all other plugins, and the issue didn’t change. The theme is: Sydney.
Thank you for that. I have successfully implemented the customizing and it rewrites the Stripe call correctly.
However, the contact form email fails to send when the Stripe call is included. If I just use the form with a standard submit, it all works correctly. When I replace the submit with the stripe call, then it successfully processes the payment, but then fails to send the message showing the “Failed to send your message. Please try later or contact the administrator by another method.” message.
Any idea what might cause this?
