I have enable the Hupso-plugin to show only in the sidebar and not on any pages or posts. This works fine.
However, I've encountered an issue with custom post types.
I am using get_posts($args) to display a number of custom post types on the front page. The Hupso share button appears underneath each of the posts. It doesn't appear beneath the individual custom post, but only in the overview generated by get_posts($args).
