Tabber sidebar not display correctly in inside page

I’m using the Tabber javascript from this page
https://www.barelyfitz.com/projects/tabber/

on the sidebar of my site https://www.quantnet.com

On the front page, it displays correctly the 2 tabs on the right sidebar (Views, Comments)

But if I click on an article (for example https://www.quantnet.com/chicago-msfm-fired-founding-director/) the sidebar display is not correct anymore. The tabs do not work properly.

I tried this with DomTab and the problem is the same, so it appears to be something with the javascript in the header.php file?

I call this in the header.php
<script type=”text/javascript” src=”<?php bloginfo(‘template_url’)?>/js/tabber.js”></script>

Thank you.
