Recently we notice an not described change in Facebook shares API that may prevent the sharing of work. The change itself may be results of the upcoming GDPR regulations. But am I having that problem on my site? The answer is that you need to test the work of Facebook share command and if you see the following message appearing than you have such problem.
Can’t Load URL: The domain of this URL isn’t included in the app’s domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.
The function that causes the problem is the closing window command after share. With that change of the Facebook API the close will no longer be an option that users will be able to use anymore – maybe this results in strongest user regulations.
What is the solution?
You need to update Easy Social Share Buttons for WordPress to version 5.5.2 or newer. The version is available with automatic plugin updates for all users that have registered the product (direct customers only) or you can update the plugin manually from your Envato profile.
