Update to 4.5 affected style sheets?

My blog appears as it should on the home page (https://linkmeister.com/dodgers/), but once a comment is added to an individual post the column text appears as centered rather than left-justified and the right sidebar floats down to the bottom of the center column (https://linkmeister.com/dodgers/2016/04/game-12-2016/#disqus_thread).

I’m using the Admired theme with Disqus comments.

Naturally I updated in place rather than making a copy of the database. My host might have a copy of the 4.4 files, come to think, but I’d like to think WP has a fix for this.

Thank you.
