Checkout not working even with a paid plan

Hey guys,
My checkout doesn’t seem to work for my store and I’m on a paid shopify plan. Whenever myself or anyone on the site tries to check out, we are met with this page:

I’ve already set up shopify payments and shipping and I have a paid plan selected but I still have 4 days of trial period before I get billed. Is there any way to fix this?

Note: I did close my store a few days ago (cancelling subscription) and I reopened it after and paid for the plan - (Does this have to do with the problem?)

Please help as I am trying to officially launch ads for my store but it would be impossible with this checkout issue.
My store url: http://www.petharbour.net

Hey @Super33323 .

Thanks for reaching out.

I appreciate that you have included a screenshot of the error message you are seeing in the checkout. It looks like this error message displays when the store is still under the trial plan. With that being said, the checkout will display this error message until the store is officially on a paid plan. You can check the status of the stores plan by navigating to Settings > Plan to see the status of the plan.

Once the trial period has ended and you are billed for the subscription of the store, the checkout will then be enabled allowing you and your customers to complete purchases on the online store.

Let me know if you have any additional questions or concerns, happy to help out.
