I’m having the same problem, and actually trying to edit the same line of WooCommerce CSS! I searched, but I don’t see the same kind of closing bracket errors in my file. I am using the Woo MyStile theme, and they recommend you put any new css in the custom.css file, so I put in
ul.products li.product { width: auto !important; }
to get it to override the file at
https://www.rijigreen.com/wp-content/themes/mystile/styles/green.css
but it doesn’t take my changes. I am trying to get it to display the product images at their actual size instead of choosing a width percentage at
https://www.rijigreen.com/shop/
I also tried manually editing the green.css file, FTPing it over the existing green.css file, and when I request that CSS file in the browser, I’m getting the old file, with no changes. But when I SSH in, the file for sure has the changes I made. I don’t have any caching plugins running at all.
What else could I be missing that would cause my changes not to take effect?
