Here’s the problem (and it’s not you) For pro or commercial product support please contact the author directly on their site. That includes free themes that are not from this site, those count as commercial too.
Commercial products are not supported in these forums. Yes, it’s free but it still counts as commercial. They sell their support.
For generic CSS support, then yes to a point you can ask for support here. But you’re having slider problems and those get complicated and are theme specific.
Please consider using a theme that is actually supported in these forums. Or consider asking Woo directly how to get paid support on their site instead.
