Django - 403 Forbidden CSRF verification failed

Question

I have a contact form in Django for my website and when I was testing it locally it was working fine but now when I try to submit my contact form "live" it always comes up with 403 Forbidden CSRF verification failed.

view:

def contact(request):
    if request.method == 'POST':
        form = ContactForm(request.POST)
        if form.is_valid():
            cd = form.cleaned_data
            send_mail(
                cd['subject'],
                cd['message'],
                cd.get('email', '[email protected]'),
                ['[email protected]'],
            )
            return HttpResponseRedirect('/thanks/')
    else:
        form = ContactForm()
    return render(request, 'contact/contact.html', {'form': form})

contact.html

{% extends 'site_base.html' %}

{% block head_title %}Contact{% endblock %}

{% block body %}

      <h2>Contact Us</h2>
      <p>To send us a message, fill out the below form.</p>

    {% if form.errors %}
        <p style="color: red;">
            Please correct the error{{ form.errors|pluralize }} below.
        </p>
    {% endif %}

    <form action="" method="POST">
    {% csrf_token %}
        <table>
            {{ form.as_table }}
        </table>
        <br />
        <button type="submit" value="Submit" class="btn btn-primary">Submit</button>
    </form>    

{% endblock %}

settings (the ones I thought would be relevant):

SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
SESSION_EXPIRE_AT_BROWSER_CLOSE = True
MIDDLEWARE_CLASSES = [
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

After trying to rule out some things, here's what I discovered. When I comment out SESSION_COOKIE_SECURE = TRUE and CSRF_COOKIE_SECURE = TRUE and SESSION_EXPIRE_AT_BROWSER_CLOSE = TRUE it works no problem.

If I just comment out CSRF_COOKIE_SECURE = TRUE it works fine. Something weird seems to be going on with how I'm handling CSRF... any help would be great.

Sounds to me like the site is not https if it works when you comment out that line? CSRF_COOKIE_SECURE=True makes the csrf token only work with ssl per the docs https://docs.djangoproject.com/en/1.7/ref/settings/#csrf-cookie-secure
