Here is my routes code if there is anything wrong there:

from flask import render_template
from app import app
from app.forms import LoginForm

app.route('/login/')
def login():
    form = LoginForm()
    return render_template('login.html', title='Sign In', form=form)

Answer 1

can you tell what is in the address bar of your browser and how you are running the app. try removing the extra slash after login in you route.
