Zeroqode forum helped me a lot last weekend.
But I faced the trouble.
I could implemented Stripe payment correctly, but suddenly I can’t.
Error message is
Stripe marketplace error: this header value for Stripe Account is not correct.
I didn’t changed Stripe workflow from the day (Stripe Marketplace Express Workflow didn't end in Debugger Step-by-Step mode)
I confirmed that the API Keys & Client IDs are the appropriate ones for Live vs Test modes, and their values do not contain any spaces before/after the actual value.
How can I fix this problem?
I am going to deploy this service the day after tomorrow, I need your help.
