 I don't know if it is reproducable yet. What I have noticed is that it
 might be related to the Events Manager plugin, because it seems to be
 occurring on events pages. But I checked their template php file, and they
 have the `have_posts()` check, so I can't figure what could be the issue.


 {{{#!php
 <?php
 <?php if ( have_posts() ) : ?>
                <article id="post-<?php the_ID(); ?>" <?php post_class();
 ?>>
                                 <?php
                     $post = get_post();
                     $EM_Event = em_get_event($post->ID, 'post_id');
                 ?>

                              <?php the_content(); ?>

 }}}


 Inside the event manager template itself then there is a `global
 $EM_Event;`

 Still not sure why this would propagate inside the code of WordPress, it
 should be sufficiently self contained.
