    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_shortcode() in wp-content/plugins/zengo-custom-thumbnail-image/display.php:280
    • > PHP Fatal error
      Uncaught Error: Call to undefined function add_action() in wp-content/plugins/zengo-custom-thumbnail-image/image.php:12

User-side errors Passed 1 test
