Compatibility with other Facebook plugins

Hi,

I am using the latest version of the plugin and while it is definitely the most wonderful login plugin, I am facing problems in using it with another Facebook comments plugin.

The other plugin essentially lets people comment using their Facebook account and post it to facebook simultaneously. (The plugin: https://premium.wpmudev.org/project/comments-plus/)

Using both together, whenever I try to log in to my site with WSL’s Facebook login, I get this error:

Fatal error: Call to undefined method Facebook::setExtendedAccessToken() in /public_html/XXXXX/wp-content/plugins/wordpress-social-login/hybridauth/Hybrid/Providers/Facebook.php on line 40

I guess this looks to me like a Javascript conflict, but am not too sure. Can you help me resolve this?
