Issue JFBConnect and Gtranslate

I was able to recreate the problem on your site but am unsure what's causing it. Can you set the "Debug Mode" option to 'On' in the JFBConnect -> Configuration area? I'm hoping that will display an error message on the site when the redirect happens that will help investigate.

Beyond that, the only other information I have now is that GTranslate seems to be overriding the 'Base URL' of your site from example.com to example.com/it That normally should be fine, but it seems that for some reason the login process isn't working at that URL. I don't have any good reasons as to why at this point, but putting that detail here so I remember.

Please let us know if you see any error messages when trying to login with Debug Mode enabled.

Thanks,

Can you go into the Facebook Developer area and edit your app. Go to the Facebook Login -> Settings area. Then, find the "Valid OAuth Redirect URIs" section. In there, you'll need to add the authentication URLs with /it/. I'm assuming you already have the ones without /it/ in there. When done, you should have all variations of your URLs like:If you have other language URLs or your site can be visited over non-www or http (not https), make sure you have those as well.

Hopefully, that will get you going!

Can you send me a picture of your settings from the Facebook Developer area? You can send me a Private Message with those details by clicking the mail icon under my name to the left.

There is likely a code change we can provide to you that would make things work, but that would be something you'd have to apply with every update to JFBConnect, so not really a great solution for the long term. I'd really like to understand what's going wrong and fix the actual cause first.

Thanks for sending the images. The "Valid OAuth Redirect URI's" setting does not have your URL with /it/ in it. Can you add more URLs, like described in the post above. You should have, at least:
I hope that's all it is,

I understand what the redirect looks like

The "Valid OAuth Redirect URI's" field can take multiple URLs. You shouldn't have to set just one. Please set them both in the app settings. It then may take Facebook an hour or more to fully recognize the setting in all of it's servers, so be patient. That URL must be set there without /it/ and with it (and any other language strings you may use).

Thanks,
