 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

    <script type="text/javascript" src="http://cdn.ucb.org.br/Scripts/formValidator/js/languages/jquery.validationEngine-en.js" charset="utf-8"></script>

    <script type="text/javascript" src="http://cdn.ucb.org.br/Scripts/formValidator/js/jquery.validationEngine.js" charset="utf-8"></script>

Use below cdn instead of above.

<link href="ValidationEngine.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<link href="//cdnjs.cloudflare.com/ajax/libs/jQuery-Validation-Engine/2.6.4/validationEngine.jquery.min.css"
    rel="stylesheet" type="text/css" />
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jQuery-Validation-Engine/2.6.4/languages/jquery.validationEngine-en.js"
    charset="utf-8"></script>
<script type="text/javascript" src="//cdnjs.cloudflare.com/ajax/libs/jQuery-Validation-Engine/2.6.4/jquery.validationEngine.js"
