'Flask Login is not working properly on Python Anywhere

This morning I tried to login in my account from my website(deployed on python anywhere). I typed my credentials and then I got a Server Error.

The Error:

Traceback (most recent call last):
  File "/home/Vomindo/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/flask/app.py", line 2073, in wsgi_app
    response = self.full_dispatch_request()
  File "/home/Vomindo/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/flask/app.py", line 1518, in full_dispatch_request
    rv = self.handle_user_exception(e)
  File "/home/Vomindo/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/flask/app.py", line 1516, in full_dispatch_request
    rv = self.dispatch_request()
  File "/home/Vomindo/.virtualenvs/my-virtualenv/lib/python3.6/site-packages/flask/app.py", line 1502, in dispatch_request
    return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args)
  File "/home/Vomindo/mysite/main.py", line 463, in logmein
    spass = check_password_hash(user.password, password)
AttributeError: 'NoneType' object has no attribute 'password'

After that, I tried to login from my main device. It worked perfectly. I checked if I entered the same credentials and I did.

The view function:

@application.route('/logmein', methods=['POST'])
def logmein():

    password = request.form['password']
    email = request.form['email']

    user = User.query.filter_by(email=email).first()
    spass = check_password_hash(user.password, password)

    if not user:
        return '<h1>We could not find the account!<a href="/login">try again</a></h1>'
    else:
        if spass == True:

           login_user(user, remember=True)
           return redirect('/')
        else:
           return '<body style="background: yellow"><h1>The password is incorrect! <a href="/login"> go back</a></h1></body>'

Thanks for help!!!

You should see whats being sent over when you post by printing the form data.

@application.route('/logmein', methods=['POST'])
def logmein():
    print(request.form)

    # print each method so you can look around
    print(dir(request.form))
    return 'test'

AttributeError: 'NoneType' object has no attribute 'password' < Leads me to beleive the issue is that password doesnt exist as you reference it.
