Try rewriting your form to something like this:

<form method="POST" action="{% url 'search' %}" class="form-inline my-2 my-lg-0">         
    <input class="form-control mr-sm-2" type="search" placeholder="Search" arialabel="Search" name="search" id="search">
    <button class="btn btn-outline-success mx-2 my-1 my-sm-0" type="submit">Search</button>       
</form> 

And your search view like this:

def search(request):
    myposts = Blogpost.objects.all()
    if request.method == 'POST'
        query = request.POST.get('search')
        if len(query) > 78:
            myposts = Blogpost.objects.none()
        else:
            myposts = Blogpost.objects.filter(Q(title__icontains=query))
            myposts = Blogpost.objects.filter(Q(content__icontains=query))
            myposts = Blogpost.objects.filter(Q(slug__icontains=query))
        if myposts.count() == 0:
            messages.warning(request, "No search results found. Please enter again.")
        context = {'myposts': myposts, 'query': query}
    return render(request, 'blog/search.html', context)

UPDATE

So, after going through your GitHub repository I saw a couple of issues, first off there is no urls.py or views.py in your blog app, its either not added in the repo or just doesn't exist, which would explain the router not finding any paths for your views, hovewer there is one in the question so I'm not sure whats the issue here, please check again so that the file is in the right directory in the root of your blog app folder.

Second off in your main project directory there are files called urls.py, views.py and forms.py, that shouldn't be the case, instead create a seperate app and place them there.
