Facebook Registration Plugin not Loading - facebook

Question

I'm using the Facebook Registration Plugin and it seems to have stopped working, but I'm not sure why. What happens is that instead of loading the registration form, it just displays the moving bars loading icon (and never loads). I have the necessary credentials, also in the past when my credentials were wrong, an error message would appear in the space that the form would normally show.
One thing I noticed was that when I visit the registration's FB page I can see the two examples without custom fields, but I can't see the example with custom fields. In my usage, I use custom fields. Maybe it has something to do with using custom fields and/or firewalls?
So right now, users can't register. Please help! Thank you!
Here's my code:
<div id="fb-root"></div>
<%= javascript_include_tag "https://connect.facebook.net/en_US/all.js#appId=myappnumberiscorrecthere&xfbml=1" %>
<% site_url = MyApplication::Application.config.site_url %>
<fb:registration
fields="[
{'name':'name'},
{'name':'first_name'},
{'name':'last_name'},
{'name':'email'},
{'name':'gender'},
{'name':'birthday'},
{'name':'username', 'description':'User Name', 'type':'text'},
{'name':'postal_code', 'description':'Postal Code', 'type':'text'},
{'name':'password'},
{'name':'captcha'}
]"
redirect-uri="https://<%= #domain + "." + site_url %>/users"
width="530">
</fb:registration>
</div>

Answer 1

Remove the captcha field.
I'm experiencing the same problem when trying to load their documentation page with custom fields and when using the code you have provided.
By removing the captcha, it seems to work. I presume there is a bug on Facebook's end.

Answer 3

change it from
fields="[
{'name':'name'},
{'name':'first_name'},
{'name':'last_name'},
{'name':'email'},
{'name':'gender'},
{'name':'birthday'},
{'name':'username', 'description':'User Name', 'type':'text'},
{'name':'postal_code', 'description':'Postal Code', 'type':'text'},
{'name':'password'},
{'name':'captcha'}
]"
to
fields=[
{'name':'name'},
{'name':'first_name'},
{'name':'last_name'},
{'name':'email'},
{'name':'gender'},
{'name':'birthday'},
{'name':'username', 'description':'User Name', 'type':'text'},
{'name':'postal_code', 'description':'Postal Code', 'type':'text'},
{'name':'password'},
{'name':'captcha'}
]"
