Answer 1

You get that error due two of the following reasons. You might see the same issue due to other reasons as well

1-You're missing / at the end of your url and you can fix it by fixed by added "/" to the end of the URL you request

2-You make some requests then quickly stop it. Like calling a url then cancelling the call and call another url. Check where do you make your calls (JavaScript or backend) and make sure you call the url without cancelling it.

This might be because you are using two method for inserting data into database and this cause the site to slow down.

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email).save()  <==== 
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')

eg. in above function error is where arrow is pointing the correct way to implement above is

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email)
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')
