shortcodes not working on pages with Enigma theme

Hello,
After installing the Enigma theme, and even by having added the following lines of code into functions.php

add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');

If I want to create a page showing last articles, say with that :
[display-posts posts_per_page="15" image_size="thumbnail" include_excerpt="true"]
The displayed result is that I can show the shortcode with ” replaced by ?
Can you help me on this, I need to create a last articles page with this theme.
Thanks.
