Not working

Hello.
In your site I see 2 jquery library including, you can check this just looking into source code of your site in your browser:
1. First around line 76:
<script type=’text/javascript’ src=’http://www.civittas.com/wp-includes/js/jquery/jquery.js?ver=1.11.2′></script&gt;
And this is correct WordPress core jquery library
2. Second – include some plugin “addon-so-widgets-bundle” around line 94:
<script type=’text/javascript’ src=’http://www.civittas.com/Contenidos/plugins/addon-so-widgets-bundle/js/jquery.js?ver=4.2.2′></script&gt;
And this is not correct, because there should not be 2 jquery libraries on your page, and all plugins should use WordPress native jquery library.
Just try to disable plugin “addon-so-widgets-bundle” or ask this plugin developers – do not include this library second time and use native WordPress library.
