For some reason on your category layouts, an extra "strong" tag is being inserted via Javascript which is breaking our CSS. Here's the top part of the code:
<div style="position: fixed; top: 300px; left: 15px; width: auto; margin: 5px; padding: 5px 0px 0px 5px; z-index: 99; overflow: visible; background-color: rgb(255, 255, 255);" class="jfbcsocialshare scsocialbuttons box_count vertical">
<strong>
<div class="sourcecoast share linkedin jlinkedShare">
That <strong> tag is not from JFBConnect or our module and (again) it's coming from some Javascript that's altering the page, so you can't see it in the HTML.. but it is there.
I hope that helps you narrow things down.
Also, I notice your subscription to JFBConnect has expired. We really hope you'll consider re-subscribing to JFBConnect soon.
Thanks,
