You have a bunch of javascript errors on your site, that are probably causing other things, like Sliders, to fail too.
The errors seem related to RSSocial.
Check your browser's console to get more info about the javascript error(s).
Could it be related to Lazy-load images as they exist on this page but on other pages like
jtbworld.com/jtb-fixrefs
where Sliders work Lazy-load images does not exist?
Note that after using a link like
jtbworld.com/jtb-flexreport#documentation
and refreshing it works.
The sliders don't seem to function at all. Not just the scrolling. But after closing a slider, it won't open.
I recommend you fix the javascript issues on your site.
