A simple plugin to style the WooCommerce Breadcrumbs or disable them altogether
You're most likely using a WooThemes theme. WooTheme themes disable the WooCommerce breadcrumbs in favour of the WooFramework Breadcrumbs and unfortunately there aren't as many options that can be configured.
Certainly! On the settings page, simply untick the 'Enable breadcrumbs' checkbox and save your settings.
