The downward facing arrow in the upper right corner has the selection for switching your FB style. Second option from the bottom should be "switch to new facebook" or "switch to classic facebook"

My FB didn't go all funky like yours, but it wasn't working 'right' until I clicked on the new version.
What happened to yours??? So were you sort of forced into the new version like me?

It stopped updating. I went to FB two days after I was last there, and nothing had changed. Signed out, signed in, refreshed, nothing changed. Gave it another day, still no change except a message to try the new FB. Made the switch and it seemed to be working again.
