Hello gm bos,

Can you try revoke your access from your backend >easyblog > Autopost > facebook and deleted your apps from your facebook > setting > apps > select your apps > delete apps , check my screenshot below

Then go to your facebook apps double check is it correct and follow this documentation
-> http://stackideas.com/docs/easyblog/autoposting/facebook-new-ui

After that go to your backend easyblog autopost configuration page, double check the apps ID, apps secret ID and page ID, if everything okay > save.
Then click Sign in with facebook. If still cant make it work, can you pass us with your Joomla backend, facebook access so we can help you check on this? Please advise.

I have all the apps and settings deleted.
I tried again to make a facebook app like your link. But i get this warning, by filling my url. And in the back end by click the facebook button i get the other warning. See illustration. :-(

Hello gm bos,

Sorry for late reply to this,
It seems like your Facebook apps is not configure correctly, you should set your App domain without http://
-> http://www.yourdomain.com
-> yourdomain.com

If you still can't make it work, can you pass us with your Joomla backend and Facebook access so we can help you check on this? Please advise.
