Hi, all.
Thank you for joining the thread and sharing the issues your customers have been experiencing with the checkout.
Shopify received reports of numerous customers being affected when moving from the Cart page to the checkout and are receiving the following error message: “There was a problem with our checkout. Refresh this page or try again in a few minutes.”
Our developers have since resolved this and your customers should be able to proceed to checkout. I recommend clearing your cookies and cache and completely rebooting the browser before proceeding.
We appreciate your patience and understanding as our developers worked to have this resolved for you.
