I am with wordpress 3.3.2 and installed the last version of the plugin. I have a quite customized theme (for example archive.php sends to different templates).
With normal options, although I ask to display there, it does not display on categories - only on pages.
What happens is the script does not load a all.
I have tried async code and other things, I am always with the same problem.
I now use a manual insertion od the buttons into my templates.
Only if I add the script manually after my insertion it works... but then I lose some parameters etc.
<!--<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=ra-4fa382503d81907c"></script>-->
Is there something I could tune in the plugin file?
