Emilio José Calvo Carrasco on "[Plugin: Wordfence Security] W3C validation fix"

Open wordfenceClass.php located on lib folder.

Edit line 1288:
$URL .= '?action=wordfence_logHuman&hid=' . wfUtils::encrypt(self::$hitID);
And replace with this:
$URL .= '?action=wordfence_logHuman&hid=' . wfUtils::encrypt(self::$hitID);

That's all.

Please fix this bug in your great plugin for the next update.

Thank's a lot for your great job.
