Django rest basic authentication issue (HTTP 400)

I am building an API which has basic authentication enabled. When I'm trying to add an instance to the database (on a viewset which has the AllowAny setting) using the browsable api it. This works when I am not logged. However when I'm not logged in it gives me an error:

HTTP 400 Bad Request Content-Type: application/json Vary: Accept Allow: POST, OPTIONS

{
    "product": [
        "This field is required."
    ],
    "buyername": [
        "This field is required."
    ],
    "buyeremail": [
        "This field is required."
    ]
}

This is the viewset:

class TicketBuyerViewSet(mixins.CreateModelMixin,  
                   viewsets.GenericViewSet):
    queryset = Ticket.objects.all()
    serializer_class = TicketSerializer
    permission_classes = (IsOwnerOrReadOnly,permissions.AllowAny)

    def perform_create(self, serializer):
        serializer.save(isPayed=False,checkedIn=False,isRefunded=False,checkedInDate=None,paymentID="",paymentDate=None)

And this is my urls.py file:

from django.conf.urls import include, url
from django.contrib import admin

urlpatterns = [
    url(r'^admin/', include(admin.site.urls)),
    url(r'^', include('events.urls')),
    url(r'^docs/', include('rest_framework_swagger.urls')),
]

urlpatterns += [
    url(r'^api-auth/', include('rest_framework.urls',
                               namespace='rest_framework')),
]

I have been having this problem only recently. I made the snippets app from the django docs which worked perfectly for about a week. However, since a couple day I have the same problem with this api as with my 'own' api. I have tried chrome and firefox as well.

Edit: While I get why the http error codes may be confusing opposed to my question I do highly suspect the error lies in the django-rest authentication because when I log out and I fill in the EXACT same data it DOES work. Here are the response error codes for the PUT request when I'm logged in and logged out respectively:

[03/Nov/2015 20:38:44] "POST /ticketsbuyer/ HTTP/1.1" 400 10513
[03/Nov/2015 20:39:24] "POST /ticketsbuyer/ HTTP/1.1" 201 4543

Edit 2: I downloaded the exact source code from the django-rest-framework-tutorial github. I created a superuser and the EXACT same thing happened, for some reason django rest browsable api or my browser is not sending the post data correctly.

Edit 3 For some reason it worked for me to downgrade to version 3.2.5 of the rest-framework. I'm not the only one with this problem: Django Rest Framework - Browsable API Form always returns 400 bad request
