I’ve had this issue across all of my WordPress sites too. I had to rollback to 4.4.0 to resolve the problem and get the sites working again.

I didn’t change the titles, and the problem exists even if I go straight to the page, e.g. http://www.willhowells.org.uk/blog/?page_id=231 – which works fine for posts.
