I used to have a facebook widget in one of my sidebars. It was an option to include since I installed the theme. Now it has disappeared and I’m not sure where it went and how I can get that widget back.
Site URL: hidden Theme version: 2.5 WooCommerce version: 2.4.10
Our theme doesn’t have Facebook widget by default. Perhaps you used some plugin, didn’t you?
Try to use any 3rd-party plugin for Facebook widget and add it to Appearance > Widgets > Single product page Sidebar.
