Every single page on the RSVP manager works, except when I click 'Assign'.
I am then led to a web page basically blank, given only the purple background and the Header. All I can see is 'My Events', 'Add Events', 'Edit Info', 'Sign Out', and the header right above it. Rest of the page is simply purple.

Before today, assigning characters has worked fine. I've turned my computer off, and restarted--nothing changes.
Is there anything to be done about this problem. . .?
