Hank here from Shopify.
When did you first notice this, or did you receive any error messages in your admin prior to the store going offline? What was the last thing you recall before noticing this message?
Or have you received an email from the accounts team at Shopify? If you had, my advice would be to respond directly to this email with any questions you may have, as they are best equipped to deal with any account queries. Note that sometimes emails will get sent to your junk/spam folder.
However, if you have not received an email, let me know, and I can look into this further for you.
All the best,
That is great to hear you were able to resolve this.
We at Shopify really aim to give the highest level of support when it comes to our merchants, so I appreciate any feedback you can give that helped you resolve this issue.
