Ok
Did the elimination excercise and found that when I switch off RSFORM PRO form, it doesnt happen, and then approached RS Joomla Forum - and this is the reply I got from them:
RS JOOMLA say: "
I don't know how exactly you came to the conclusion that this is definitely RSForm! Pro's fault when you have the following script straight on your homepage:
<!-- Responsive stacking order -->
<script type="text/javascript">
jQuery(document).load(jQuery(window).bind("resize", listenWidth));
function listenWidth( e ) {
if(jQuery(window).width()<959)
{
jQuery("#sidecol_b"
.remove().insertAfter(jQuery("#content_remainder"
);
} else {
jQuery("#sidecol_b"
.remove().insertBefore(jQuery("#content_remainder"
);
}
if(jQuery(window).width()<959)
{
jQuery("#sidecol_a"
.remove().insertAfter(jQuery("#content_remainder"
);
} else {
jQuery("#sidecol_a"
.remove().insertBefore(jQuery("#content_remainder"
);
}
}
</script>
"which actually removes your content. I don't know what that script should be doing (I'm guessing it's to create a responsive layout, although I don't think Javascript should be used in this case) but it's clearly not doing it right.
Without that script your website runs fine."
