PHP Catchable fatal error: WP_Error could not be converted to string

Since we updated to 4.0.0 when non-logged-in users submit a comment, they just see an error message and the comment will not be posted.

PHP log:

PHP Catchable fatal error: Object of class WP_Error could not be converted to string in /var/www/web_1712_1/htdocs/live/wp-content/plugins/wp-ulike/inc/general-functions.php on line 1864

We did a var_dump($num) on line 1864 and got:

object(WP_Error)#12449 (2) {
  ["errors"]=> array(1) {
    ["broke"]=> array(1) {
      [0]=> string(47) "Please enter some value for required variables."
    }
  }
  ["error_data"]=> array(0) { }
}

So our temporary workaround was:

if (is_a($num, "WP_Error")) {
  $value = '';
} else {
  $value = $num . $sign;
}
