It could be that some other script on the page is interfering with the addthis script... or it could be due to modifications your developer made to the bulletproof template.
Another possibility would be to use a newer addthis code. Your template should have a file named entries.tpl, and in that file, will be this:
Code: Select all
<div class="addthiswidget">
<script type="text/javascript">
addthis_url = '{$entry.rdf_ident|escape:url}';
addthis_title = '{$entry.title|escape:url}';
addthis_pub = '{$template_option.addthisaccount}';
</script>
<script type="text/javascript" src="http://s7.addthis.com/js/addthis_widget.php?v=12" ></script>
</div>
You could try changing that to this:
Code: Select all
<div class="addthiswidget">
<a href="http://www.addthis.com/bookmark.php?v=250" onmouseover="return addthis_open(this, '', encodeURIComponent('{$entry.rdf_ident}'), encodeURIComponent('{$entry.title|escape:url}'));" onmouseout="addthis_close()" onclick="return addthis_sendto()" title="Bookmark and Share" target="_blank"><img src="http://s7.addthis.com/static/btn/lg-bookmark-en.gif" width="125" height="16" alt="Bookmark and Share" style="border:0" /></a>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js?pub={$template_option.addthisaccount}"></script>
</div>
