Shortcode label widget not working


Hi, I’ve installed a new template on my blog annapernice [dot] com . Some widgets (in particular home widgets in which should be shown the last 5 articles for labels and the slider with recent articles) needs shortcode, but it seems that my website don’t read them. I’ve tried to install the tutorial for shortcode widget on your website, but it don’t work yet, maybe because it’s for videos and photos, while I need a shortcode widgets for label. Where can I find it? Could you please help me? Thank you very much Anna
