Your account is inactive

Hi guys!

Does anyone else have the same issue: users are getting the "Your account is inactive" error. I've checked the administrator account, and all users are active. Subscriptions are active, and all invoices are paid. Moreover, I can't even contact support now. Support is not available in chat or by phone, and no notifications have been sent to my email. I don't know where else to turn; maybe I can find answers to these questions here.
