Are you using AdBlock, Facebook Disconnect, or another browser extension that blocks Facebook Connect?

Try disabling it. This is likely the reason, especially if you don't see a "login" button.

Check if you have blocked NetworkedBlogs on Facebook

In Facebook, from the menu in the top right corener:
Click "Privacy Settings" -> Blocked People and Apps -> And make sure NetworkedBlogs is not blocked.

Could it be something else in your browser?

As a test, try accessing this page with a different browser. If it works, then there's something in your extensions or settings that is causing the issue.

If that doesn't fix it, email us at info@ninua.com.
