When I put the Wordpress Search widget anywhere on the site, it doesn’t work. It shows whatever I’ve titled it, but doesn’t insert the search box. I briefly switched to another theme and it worked fine, so it must be a conflict in the UUA theme. 
Just to show an example, I put it above Upcoming Events. As you can see from the linked image below, it’s just the words. I’ve tried it many different places with the same results. Thanks!
