I'm using the UUA Congregation theme version 1.1.2. On pages where I use the uua_staffer shortcode I noticed the menu on the left disappears, and the "breadcrumbs" on the top incorrectly say the name of the last staff member whose entry was displayed instead of the name of the page. After some poking around I was able to fix the problem by modifying uua-congregation/lib/shortcodes/uua-staffer.php to change line 77 from: <code><?php endwhile; ?></code> to: <code><?php endwhile; 
wp_reset_postdata(); ?></code> Looks like the old version of uua-staffer.php did that, but it was left out of this version.
