Hi andrewwinkler
Your website is running on https protocol and is returning unsecured content because you are serving links with http , this could cause some problems on your website , regarding the countdown module you can fix them editing this file modules/ja-countdown-module-for-joomla-2-5-3-4_1.0.7/tmpl/layout1/js/jacclock.js
find :
var timeurl = "http://www.timeapi.org/utc/now.json?callback=?";
change to
var timeurl = "https://www.timeapi.org/utc/now.json?callback=?";
repeat this step for each layout file
also you can use the developer console and correct other http errors on your website
at least you can exclude this as an error source
hope it helps
