universityofmauritius Hi
Preloader effect is added via css in this file /templates/gk_university/css/gk.stuff.css
.gkIsWrapper-gk_university .gkIsPreloader {
background: #3f4e67 url('../images/style1/is_loader.gif') no-repeat center center;
height: 100%;
left: 50%;
position: absolute;
text-indent: -9999px;
-webkit-transform: translateX(-50%);
-moz-transform: translateX(-50%);
-ms-transform: translateX(-50%);
-o-transform: translateX(-50%);
transform: translateX(-50%);
width: 100%;
z-index: 100;
}
You can disable it adding to the custom.css via template editor Advanced Setttings Tab
.gkIsWrapper-gk_university .gkIsPreloader {
display:none!important;
}
Hope it helps
