Answer 1

It is caused by plugins or themes calling the_content() outside of the Loop, where $pages = null. This will cause php 7.2 to throw an error if attempting to count non-countable types.

In your case you must put your the_content() function inside the main loop like this:

if ( have_posts() ) {
    while ( have_posts() ) { the_post();

        the_content();

    }
}
