Why do my Facebook Likes disappear from my Wix site pages?
The Like button counter is associated with the URL address of the page it has been placed on.
It is not possible to associate a Like button, which already has "Likes", with a new URL. Therefore, changing the URL of a page will result in losing that page's existing "Likes".
The Facebook Like counter is provided by the Facebook API. This applies to the Facebook Like app provided by Wix, as well as Facebook's code used to generate the Like counter using the HTML App.
Important: The new Facebook improvements to Like button API will automatically remove Likes gained by malware, compromised accounts, deceived users, or purchased bulk Likes. To learn more, click here.
