With the plugin, probably not.
But you can do without a plugin, and then it would work.
- deactivate the plugin
- edit your header with that code above the </head> part :
<script type="text/javascript" src="http://apis.google.com/js/plusone.js"></script>
- edit your template's single.php (the pages of the posts) and add wherever you like
<g:plusone size="medium"></g:plusone>
You may edit the "medium" size as you see fit, ask Google precisely if you want more.
And if you want to toy with more advanced settings, this is the way to avoid having something - like the google +1 button - to be shown on the index page, and to be shown anywhere else :
<?php
if ( is_home() ) {
echo '<g:plusone size=small></g:plusone> ';
} else {
// do nothing
}
?>
