Hi there -
Is there a way to get Jetpack sharing buttons showing in certain chosen widget content areas with your plugin? I am using iThemes Builder on this dev site: http://victorybox.org/ and I have placed the shortcode in the widget content area in the widgetized footer at the bottom of the page, but it doesn't show.
Here is an article from iThemes codex about placing Jetpack sharing buttons in widget content areas:
I have enabled my Theme settings as indicated in the above article to use the the_content filter to format Widget Content entries. They still do not show.
