 Replying to [comment:108 jcdev518]:
 > I know this has been marked as "completed" but I ran into a similar
 issue with PHP 7.2 this many months later.
 > Same error, but on line 310 of post-template.php after calling
 get_the_content() outside of the main loop. This is in a singular page
 template where $post is already global.

 Thanks! I've seen this mentioned on support forums as well, and created a
 follow-up ticket: #47824.

 Yes, that's the correct way to solve it for now.
