Here's a big one.

I can get into the ModCP but not the AdminCP. Half of the back office is restricted. There's a pop-up that asks to authenticate the login credentials (instead of the browser form like it used to be and the ModCP still maintains) and then breaks down into an error 401 claiming the browser does not know how to forward the credentials appropriately. I'm assuming this is tied into the recent updates during my absence.
