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.

Answer 2

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('/')
