 * Hi, I’m using MC Tag Map to generate a page for our (far too many) tags. Today
   we were hitting a 502 error on the page, which I fixed by upping the minimum 
   count on the shortcodes. However in looking at the page I noticed that Query 
   Monitor was showing a warning for the plugin:
 * Warning strstr(): Empty needle 1,208
    wp-content/plugins/multi-column-tag-map/
   mctagmap_functions.php:717 strstr() wp-content/plugins/multi-column-tag-map/mctagmap_functions.
   php:717
 * Just reporting it here, maybe you can fix it?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fstrstr-empty-needle-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * [@kip-kniskern](https://wordpress.org/support/users/kip-kniskern/) try version
   17.0.23 and see if that fixes it.
