How do I add Facebook comments to my Wix Site?
A Facebook Comments box allows your visitors to leave comments on your site by logging in with their Facebook account.
To add Facebook Comments: From the left side of the Editor, click the Add icon > click Social > click Facebook Comments.
Click the Facebook Comments box to select it > from the pop-up menu, click Settings > under Number of Comments, choose the number of comments you wish to display > under Color, choose Light or Dark.
Each Facebook Comments box that you add will be connected to the page on which it was added.
