Hi Monica,
Actually the "Renew Token" button does not work anymore. Can you try to use the "Revoke Access" button instead and then try to sign in Facebook autoposting again and see how it goes? Thanks.

if I do what you have given me, I get this message: URL bloqueada: This redirect failed because the redirect URI is not whitelisted in the app’s Client OAuth Settings. Make sure Client and Web OAuth Login are on and add all your app domains as Valid OAuth Redirect URIs. After that is connected and the button renew token appears again.

It seems like Facebook detected your current site domain is not match from what you set the domain name at your Facebook app, can you provide us with your Joomla backend and Facebook access so I can help you solve it now?

You can put your site and Facebook details in this first post, to do this you have to edit your first post then put these details into additional message area.

Thanks, I just set and the error message no longer appears, but still appears the option to renew token.

Ok thank you very much.

You are most welcome, glad that your issues are resolved now
