Remove Sidebar on Product Page not working!

It can likely be hidden with CSS but I’d need a link to the site.

I’ve taken down my site off of maintenance mode and also the shop, but can still be accessed at

https://perishedpets.com/taxidermy-shop/

I’ve been trying for HOURS to resolve this, it’s doing my head in, so any help would be amazing, thank you! @mikejolley

.woocommerce #sidebar {display:none;}

I think I already tried this, unless I put it in the wrong place, I’m not that great with coding, do I put this in my themes style css ?

Many thanks

IT WORKED!!! THANK YOU SO MUCH!!!!!!!
