'An error occurred. Please try later' message on Facebook authentication dialog

Question

I am a newbie who is trying to create a Facebook app using PHP and Facebook's PHP SDK. The app is hosted on Heroku, and the sample app that they provided is working fine. However, I am now trying to get the sample app to work on Apache 2.2, and I have encountered a lot of problems along the way. Well, straight to the point, my latest problem will be trying to do Facebook login on localhost, but the 'An error occurred. Please try later' appears on the popup dialog. This does not happen on Heroku.

Will someone please enlighten me on if there's any steps that I can take to overcome this error? I don't think it got to do with any coding error since I am just following the provided sample app. Thanks!

Answer 1

This is happening because FB does not recognize the URL of the host issuing requests. You need to determine what the FQDN of your localhost server is then add it to the Site URL section of the FB App Settings manager. Chances are you have the URL of your Heroku server in there now.

Answer 2

its simple. in local host you must create another sample application for localhost in facebook .and you must have the permission.then you can login and work with your local one.

simply for every copies of your app.you must create it in facebook

hope it help you

good luck
