Has anyone else had this problem? I'm getting this error when trying to authorize a user via FB, I think I've isolated it only when a user has installed the Facebook app:
fb_our_appID://authorize#error=unknown%5Ferror
If you delete the FB app from the user's phone, our app will then try to authenticate via Safari, and everything works fine.
Thanks so much.
Try refreshing your browser or reopening the site; on a mobile app, close and reopen the app. You can also check to see if Facebook is offline and then restart your device, update apps, and clear your cache.
If you're having trouble logging into your Facebook account from your Facebook app: Make sure that you have the latest version of the Facebook app, or delete the app and then reinstall it. Try logging in from a mobile browser (example: Safari, Chrome).
If you are having issues with the Facebook app on your iPhone device, the first thing you need to do is to quit and relaunch the app. Doing so will dump app's cached files that's preventing the app to work properly.
Yup, we were getting this as well.
It occurs when your bundle identifier does not match the one configured as part of your facebook application. Copy your bundle-id from your plist, and update the iOS Bundle ID value on facebook
