Hello,
Sorry for the problem with the maintenance message. Without being able to see your site or your account files, we can only guess at the problem. I would first suggest making sure that you have cleared your browser cache files as it may the problem. Internet browser caches can save pages that you have previously viewed. If that doesn't help, then we would need more information about the account or website that you're trying to view. Version of software you're using, a URL, and steps to duplicate the problem would be info we could use to troubleshoot the problem.
I hope that helps to answer your question! If you require further assistance, please let us know!
Regards,
Arnel C.
