Can't get into Upfront on homepage

Hi, something's up where I can't get into Upfront on my homepage. For months, it has loaded super slow (sometimes, not at all). Now, I have a faded brown screen. I can add draggable elements to it but I can't edit any text in them or get "into" them.

I NEED to be able to edit my homepage (there's a misdirected link). Please help.
