Hello Diego.

If you want to use default fb login you need to turn off Render jfbconnect buttons.

If you still hit this issue after turn off this option, can provide us with your joomla backend and FTP access?

Hi, i fill the details on post. See my site i use JFB without problem now i turn off jfb and turn on native facebook, and receive "Hay un error recuperando tus detalles de Facebook. Facebook devuelve un mensaje de error: "An active access token must be used to query information about the current user." Note that jfb is working fine. This is the test site but is configured on Facebook.

Hi Diego Fabián Hagopian,

I am really sorry for the delay of this reply as it is a weekend for us here.
I've tried to access in your test site Joomla backend, but i hitting this :

Warning

You do not have access to the Administrator section of this site.

May i know do you want to use Easysocial Facebook login or JFBconnect?
Also can you provide us with your Facebook account access which configure this Facebook login as well?
