 * I’ve just installed the plugin, and am now getting this error on all the site’s
   admin pages:
 * Notice: Trying to get property of non-object in /srv/www/htdocs/wp-content/plugins/
   content-cards/content-cards.php on line 724
 * The plugin still works, and the error isn’t visible on the non-admin pages. Is
   there any way I can get rid of it?

 * Update: upgraded PHP to 5.6.34, error still present. OS is OpenSuSE Leap 42.2,
   in case that helps.
