Where did my folders go??

Where did my folders go??

After reading and sending many emails all evening, opening and closing the website many times, when I tried to open my mail again shortly after midnight last night (6/23),  or maybe 1 am, the formatting of my mail changed. I presumed you were doing some kind of site update and that everything would be sorted out in the morning, but I see no improvement. All of my mail folders disappeared and my inbox does not display. All I can see on the side panel is "Folders, labels, views: unread, all messages, flagged." If I click on one of the views, I can see my email. But I can't minimize or maximize the folders, they're just gone. And I can't see any sent mail for that reason. The "Compose" button doesn't work. I can, however, see and access all my folders from the dashboard. From the dashboard I can compose replies to messages, but the "send" functions do not work. I can only save drafts. But when I go into my drafts folder, I can't send any of them. The only way I've been able to send mail today is through the mobile site, which is working fine. And I can't compose any new messages from the dashboard. I can only compose and send messages from the contacts page, which is not helpful. Even the search box isn't working on the main page. And there may be other problems I haven't discovered yet. Can somebody please fix this!? Help!
