Cataract theme - social icons not clickable/linking

I’m wanting to add social icons to the banner area on my site.

I’ve added the html to the sidebar following the Cataract instructions and set the banner to be displayed.

The icons are visible but the links don’t work.

I also have a twitter widget and image in the sidebar - are they interfering in anyway?

Sidebar code below:

<div id="myExtraContent5">
<div id="socialIcons">
<a href=""  class="zocial icon googleplus flat" ></a>
<a href="" class="zocial icon twitter flat"></a>
<a href="" class="zocial icon facebook flat"></a>
</div><!-- #myExtraContent -->
<a class="twitter-timeline" href="" data-widget-id="643455267326324736">Tweets by @rousantsherwood</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);;js.src=p+"://";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
