Hi to everyone, Recently WordPress Social Invitations v2.5.1 has been released to public. If you are updating your old version be sure to review the configuration docs to update your Google, Twitter, Yahoo and Foursquare providers with the new callbacks urls.
Basically we changed the way the library is included on the plugin to keep it updated with the latest changes, so now callbacks urls are slightly different.
If before you were doing something like /wp-content/plugins/wordpress-social-invitations/hybridauth/?hauth.done=google now you do instead /wp-content/plugins/wordpress-social-invitations/hybridauth/hybridauth/?hauth.done=Google
I hope we don’t create much trouble, but things will go smoother after this new release as you already now, we recoded plugin from scratch to improve performance
