Hi @clinista
I didn’t see the previous state of your page. But I checked the earlier linked page now, and I can not see any Smart Slider 3 sliders appearing there, however the JavaScript error is still present:
Uncaught ReferenceError: TweenLite is not defined
So I assume the empty space you saw, came from the slider indeed as this JavaScript error stopped our code from running like my colleague mentioned. This error may cause problems for other JavaScript codes, too. So removing the slider now probably fixed that empty space, but this JavaScript errort may cause similar problems in the future for other plugins, too.
Did you see the mentioned JavaScript error in the console:
when you disabled LiteSpeed Cache? Since I can also see that the JavaScript files on your site are combined by LiteSpeed cache, and that may cause problems for certain JavaScript codes on your site.
If the JavaScript error no longer in the console, then you could publish your slider to the page again, and it will most likely appear fine.
And if you would like to continue using LitSpeed cache, you probably need to disable their “JS Combine” feature:
as that probably causes problems for other plugins on your site, and that is why the JavaScript error occurs.
