pages disable after wordpress update

I had just changed the version number in version.php back to 4.5.3 (was playing with wp-cli but don’t ask why, LOL) and saw this exact error — Googled it and saw this post.

My bet is your version.php didn’t get updated. Look in it and check the version number to see if it is what it should be.
