Comment (by Abigailm):

 This comment is also added for informational purposes:

 I am also still seeing this error, now with a reference to line 310 (PHP
 7.3, WP 5.2.1).

 In my case it is tied to the enhanced search plugin, Relevanssi -- and
 occurs if the plugin option for "Create custom search result snippets" is
 enabled.  This has been a consistent issue for me --- but I don't know
 whether it should be seen as a problem with the wordpress core template or
 with the coding of that particular feature of the plugin.

 The error appears to be tied to this line of code in the plugin:


 {{{

         /** This filter is documented in wp-includes/post-template.php */
         $content = apply_filters( 'the_content', $content );
 }}}

 So basically, the plugin is calling the apply_filters function that is
 coded into post-template.php ... and somewhere along the line that
 generates the PHP "implements Countable" warning in some (but not all) use
 cases.
