How to enable Facebook login

Sanguine

Many FreeFlarum users want to activate Facebook login, but there doesn't seem to be an up-to-date guide as of yet. Also, Facebook now requires a public privacy policy before you can activate your FB login. So follow these steps to get rollin' !

First, create (or copy from somewhere) a privacy policy. You can just create a new discussion and use that.

Go to https://developers.facebook.com/apps/ and press "Add new app"

Enter your forum name and email

Go to Products and add Facebook Login

Go to Settings > Basic.

Copy the App ID and App Secret.

Add domain names (make sure to add both the "www" and non-"www" version if applicable.

Add site URL. Use http or https, whatever you have standardized on. Use trailing slash, like this: https://myforum.com/.

Add the privacy policy URL (noted earlier)

Go to Settings > Advanced. Add your domain to "Domain Manager" including http(s) and trailing slash.

App review -> "Make Public"

Go to your Forum admin panel. Go to extensions. Enable the Facebook extension. Enter App ID and App Secret as noted earlier.

In some cases, you have to run a php flarum cache:clear and rm assets/rev-manifest.json in the shell as a last step.

Your facebook login should work now!

(NB. will add more screenshots later)

In between this process, there's also a step to enable your App status to "On". Many people set up everything but forget about making it live and it doesn't work, so make sure that you do that as well.

Just in case you face any problems with Facebook Login try adding to your url (in Facebook settings) /auth/facebook

I was getting "URL Blocked: 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." error and going with the solution provided by gozen and jeff-kilbride fixed it for me.

Just to clarify:

In Facebook Login -> Settings -> Client OAuth Settings -> Valid OAuth Redirect URIs, that's where I had to add https://mydomain.com/auth/facebook.

I also had to edit vendor/league/oauth2-facebook/src/Provider/Facebook.php and comment out line #111, as discussed here: https://discuss.flarum.org/d/7111-login-signup-facebook-ext-error. Obviously, that "backwards compatibility" version check isn't working correctly...

jeff-kilbride You also must add https://mydomain.com/auth/facebook to Domain Manager under Settings > Advanced > Domain Manager so that it passes Redirect URI Validator.

I am getting this error:

Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.

I have added www.seekadventure.net and https://www.seekadventure.net

Are there more I should be adding?

MikeJones Have u done the suggestion by Felli: You also must add https://mydomain.com/auth/facebook to Domain Manager under Settings > Advanced > Domain Manager so that it passes Redirect URI Validator. I did the suggestion and it worked

DerrickKorku This was a lifesaver. I kept thinking I had done everything right and this was the step I had forgotten.

After - php flarum cache:clear - my site is down 🙁

I got some error messages like:

PHP Warning: file_put_contents(/home/ro/web/freelance.2winners.com/laravel/public/assets/rev-manifest.json): failed to open stream: Permission denied in /home/ro/web/freelance.2winners.com/laravel/vendor/league/flysystem/src/Adapter/Local.php on line 200

and if I change permissions rev-manifest.json to 777 and try php flarum cache:clear again - no errors -but site is still down (((

sudo chown -R <user> /home/ro/web/freelance.2winners.com/laravel

I made all the changes/steps however when I try and login with facebook, says my app domain isnt there, despite me adding the forum url

"Can't load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and sub-domains of your app to the App Domains field in your app settings."

Up2Vex You need the ssl certificate. Your urls must be HTTPS.
