Not showing in sidebar

if you are trying to add the shortcode to a textwidget, you might need to add this to functions.php of your theme:

add_filter('widget_text', 'do_shortcode');

otherwise, please describe how you are using the plugin in the sidebar.

That did the trick, but the styling is off a little. Nothing I can’t fix on my own, though. Much appreciated! And thanks for the great plugin.

As alchymyth said you have to add the filter.

Once you have that, I now added some css to 1.37 that will size the coupon correctly if inside a text widget on the sidebar.

Thanks for using the plugin.
