It’s been a while since I fixed mine, but from what I can tell I went into the templates folder to find the CSS file: cyclone slider 2 > templates > dark > style.css
So it depends which style of slider you use (I was using dark. In there you will see
.cycloneslider{
position:relative;
margin-left:auto;
margin-right:auto;
}
I think this is right, I’m not so good at this myself.
Hope this helps,
Louis
