Hello,
Edit the same file and remove the excerpt for the list mode http://prntscr.com/oj18mq
1) Provide us with Dashboard access to your site, we need to check the settings.
2) Use the custom code
div.quantity .minus {
border-radius: 50px 0 0 50px;
}
div.quantity .plus {
border-radius: 0 50px 50px 0;
}
3) Do you want to disable it for the shop page only then go to Theme Options > Shop > Product Styles > http://prntscr.com/oj1b8e If you want to disable option to buy the products for the whole site then enable Catalog mode http://prntscr.com/oj1bxd
