WineDesign

Does anybody know if there is something going on at Squarespace at the moment that's causing the editor to behave dysfunctionally? I manage a one pager website for a wine import co. with black backgrounds on header and footer. I just had to log in today to edit some content, and to my surprise the header background is now white, and no amount of resetting it in the 'edit this section' dialogs will get it back to black. Nothing worked. Resorted to loading a black logo so at least the site shows a logo at the top. Additionally, the site footer with contact details is difficult to edit - every time I make a change, the page shoots back up to the top, so I have to scroll back down to do any more work. But the worst is the footer disappears after saving the page and exiting the Editor. When going back into the Editor, the missing footer reappears, only to disappear again after exiting the Editor. It's missing on the live site now. Anybody have a clue of what is going on at SS? I doubt the problem is my Macbook Pro, I've restarted it just to make sure but the behaviour in SS continues while everything else on it is functioning fine. Including another web CMS I need to use for editing other websites.
