Comment (by aclassifier):

 This morning all was back to normal! It updates both after Page and Post
 Update.

 But yesterday I was struggling with a problem where I was not able to log
 in. A summary of that is at my blog,
 [https://www.teigfam.net/oyvind/home/publishing/061-wordpress/#wordpress_53_big_image_2560_threshold_not_wanted].
 I tried to solve that, first by disabling all plugins, and enabling them
 again. Restoring Jetpack was not that easy, there was a lot of buttons to
 press and having it see ssl again. But it stopped complaining at some
 point when I pleased it. (That's how it feels). More below. I kept
 TwentyTwelve all the time. But I was still not able to log in, but did get
 an error message pointing to functions.php: I then went in via ftp and
 restored to my old TwentyTwelveChild functions.php, effectively not seeing
 this line any more:


 {{{
 <?php add_filter( 'big_image_size_threshold', '__return_false' );?>
 }}}


 But this may be another problem. The white screen after Update was there
 before I started with the add_filter matter that messed it all up with not
 being able to log in. But even this was after some time. The not filtering
 large file was indeed working with that code line for some time!

 Another matter, which I guess adds even more smoke: My WordPress runs on
 one.com. I had been there to see which PHP was running, ''because of this
 update problem''. It had the "latest stable" which is 7.3. At some point I
 told it to use 7.4 which it called "beta" and then after some minutes I
 could not see any change, so I went back to 7.3 again. It is set to update
 automatically when 7.4 becomes "stable".

 Both my own teigfam.net and wordpress. com and wordpress.org have had all
 infocapsules available for them all the time.

 Now I don't have any secrets, but I may have smoked this too much. As a
 programmer myself I have no clue what might have caused this to have
 become fixed. Right now it seemed like it was fixed by itself over night.
 Which is when I used to laugh by myself. No magic here, but almost.
