Invalid Scopes: offline_access. This message is only shown to develope

I don't see anywhere in the JFBConnect code that we request the offline_access permission. Please check JFBConnect > Configuration > Facebook area to see if there are any values in the 'Additional Permissions Request' setting. The access_token permission is deprecated now and should be removed if set.

Additionally, when I run the Autotune Error Check on your page, I receive the following error:

Test: Facebook Javascript library inclusion
Fail: Another Facebook extension is installed, including the Facebook Javascript library, and may conflict.

Please see www.sourcecoast.com/jfbconnect/docs/common-support-questions/ for "What do these Autotune Error Check errors mean?" on how to resolve this error.

Please make sure you've disabled the "sh404SEF - Social" plugin in the system group. I may be slightly off about the name, but that should fix the Autotune error.

I hope that helps,

login is not working I gues ?

What isn't working? Please give as much information as you can.

How are you trying to login (what social network or with Joomla credentials)? Are you seeing an error? Etc.

Once we know what's happening, that will help us help you.

Thanks,
Alex

Could you try disabling the language switcher on your site and retry logging in with FB?

1.1) Please see the language answer below.

1.3) Something seems incorrectly configured with CB. If I'm logged in and try to go to the following URL, which should show the standard Joomla user component's 'logout' layout, I get a 404 error as well:
index.php?option=com_users&view=logout
Redirects to:
component/comprofiler/logout

That's something wrong with how CB is setup, and there's likely not anything we can do in JFBConnect to fix it.

1.4) Can you double-check the "Joomla user redirection" setting in the SCLogin module and make sure it's set to a page that is accessible and exists? Also, try setting that option to 'Same Page' to see if that works properly.

2) In the backend I can only select Sourcecoast login, I like to use it with community builder instead of sourcecoast login

I'm unsure what you mean here. It sounds like you don't want to use the SCLogin module. If that's correct, you can use the CB Login module and simply add the {JFBCLogin} tag to their login layout file. That will add the social login buttons to the CB Login module.

3) I have tryed to disable language, but there is nothing about language enabled. I have only the Dutch language file and the english language file.

Something is adding the /nl to the URL. Can you check if you have the System - Language Switcher plugin enabled? If not, please let us know how the language is set for each user on your site.

Thanks,
Alex
