Hello,
According to item 3, you didn’t allow our application to access to Facebook token to get reviews from Facebook.
With a probability of 99%, the problem is that in your browser disabled cookies for external website or you were disagree WidgetPack app permission after clicking of ‘Connect to Facebook’ button.
In order to make this plugin work, you need to enable cookies for external sites and try to click again on the ‘Connect to Facebook’ button in the widget, then in the opened window to agree WidgetPack application.
By the way, in the plugin description we have information about the request of this right: Keep in mind that plugin requests Facebook permission manage_pages to read your page reviews and show it in the widget.
This request of permission is absolutely safe and secure, because our WidgetPack application doesn’t get private information, this app get only Facebook token to have possibility to get reviews by this token according to Facebook API: https://developers.facebook.com/docs/graph-api/reference/page/ratings/
And by the way:
1. This is the only legal way to get Facebook Page Reviews and show them on the site;
2. Before release of this plugin we expected from Facebook about two weeks the permission to use manage_pages right, I mean that our application is completely legal and there was no one case of any problems with use it.
Thanks!
