Undefined variable "out"

  • In button/add_button.php the variable “out” is not defined.

    At line 91, out is concatenated:

    $out .= '<div class="infographic'.$settings[0].'" data-embed="'.$settings[1].'" data-code="'.$settings[2].'">
          <img src="'.$infographic->thumbnail_url.'">
          <h4>'.$infographic->title.'</h4>
          <div class="infogr-hover"><span class="infogr-h-add">Embed</span></div>
        </div>';

    But was never previously defined. I patched locally, just needs $out = ''; defined before the for loop starts on line 77
