From within the AddThis settings in the WordPress Admin area, I am trying to build a custom AddThis Twitter Button. My goal is to use something like this:
<a class="addthis_button_tweet" tw:hashtags="#hashtags"></a>
However, when I save the settings, the tw:hastags portion of the button is removed. The rest of the of the code remians. Other attributes, such as tw:text work as expected. Is there something simple that I am just missing?
