Fail: Another Facebook extension is installed, including the Facebook

That actually is an false positive in our tests that I've never seen before. Your site is including the following file:
plugins/system/omgshortcodes/assets/js/all.js
The Javascript library is also named all.js, so our Autotune checker believes another instance is being included.

With all that said, you can safely disregard that error message. Of course, if you run into any functional issues on your site, let us know, and we'll gladly help however we can.

I'm not sure what feature you're looking for, actually. If you want to add authentication to your site, you need to enable and display the SCLogin module somewhere on the page. If you're looking for something else, just let me know what feature you're trying to configure, and we'll gladly help however we can.

Thanks,

The SCLogin module wasn't loading because it was set to "position-7", which doesn't exist in your current template. I moved it to "sidebar-1" and it shows just fine.

Please test again and let me know if you still have any issues.

Thanks,
Alex

I'm not sure what you're looking for there. You want the login area along with social login buttons to appear underneath every single post? Honestly, that's not something we'd recommend as it'd get pretty cluttered.

There are ways to add the social login buttons to any section on your site by simply adding the {JFBCLogin} tag to the output. You could add that tag to EasyBlog template files to add the buttons after each post, but again, I'd really recommend determining exactly what you're looking to do and (most likely) just using the SCLogin area in one ideal module position on your site.
