Widgets wont move

This may be something related to my template, wondering if any other www.remarpro.com users experience this. Using both Google Chrome and IE 10, the Widgets will not ‘move’ to the right sidebar. The site is https://sc.com.mt but also having trouble on https://maltaportal.biz and https://vector-informatics.com our main site where we are testing it. They use different hosts but the problem is the same, indicating it’s either the template, or wordpress version, or a combination. Please help!
