I migrated from one server to another and my slider seems to have broken. If I display the full width site, the slider leaves a gap on the right side. If I resize the browser it fills correctly. It works on my old site just fine.
Your new site seems to have a value for width of one of the columns which is not the value specified in the original theme files, nor on your old site.
The current version of the theme (and every version there has ever been) is different to your new site. The file in question is \extend\layouts\responsive-1.css. It has been changed by someone at some point because this file is different to that supplied with theme.
Please upload a fresh version of the theme. The current version is 3.5.
