Loading page items stops just after widget conaining shortcode

I used WP-Content reborn to add a slide show for featured posts/pages in the frontpage. I added the plugin shortcode to a widget in desired block (my theme supports shortcodes in sidebar widgets). The result was a page truncated and items stopped to load just after the first featured post was loaded.
