I'm using your plugin on my blog and it works fine. The content of the RSS feed is displayed on my page.
But when I try to use the [sil_rss_list_blogs] shortcode on the sidebar (using a text widget) to list the names of the blogs, it doesn't work. The name of the shortcode is shown instead of the list of the blogs.
Other shortcode plugins installed on my blog are working on the sidebar. Any idea ?
