Hey there, @JohnDoe2613 !
Ryder here, from the Social Care Team at Shopify. Thanks for posting! There could be a few different reasons why you’re seeing this error, and I’d have to take a closer look at your account to be sure. Often this error message is received because you haven’t selected a plan yet, or because you’ve paused your store. In both cases, your checkout will be disabled.
If this isn’t the case, I’d be happy to take a closer look at your account. I’ve gone ahead and sent you an email to the email address associated with your Community Forums account. Once we’ve had the opportunity to authenticate you, we can continue investigating your shop’s checkout together through there. Hope to hear from you soon!
Cheers.
