I have had this working for a while and now all of a sudden the same exact code is causing some issues. I am using the following code to hide the twitter and google+ counts.
<a class="addthis_button_facebook_like" fb:like:layout="button_count" fb:like:width="47"></a>
<a class="addthis_button_tweet" tw:count="none"></a>
<a class="addthis_button_google_plusone" g:plusone:size="medium" g:plusone:count="false"></a>
Now all of a sudden the counters are showing in IE9 Compatibility mode and IE7. All other browsers seem to be working correctly. Any idea why this would be causing issues all of a sudden?
