Jinja Statement ( {% for loop%}) cannot be read on line server - html

I deployed an ecommerce website on the live server using heroku but having issue with product images as they are not being displayed.
The website is working fine on the local host but causing problem when being deployed online. I inspected the html code and found out that the live website doesn't show the jinja for loop template which is added to the html file. Can anyone please guide me on how to solve this issue?
Here is the link to the website,https://ahad-ecommerce-website.herokuapp.com/ and also the code snippet for the html file
main.html

Flask + Jinja2: left-aligning a table below a nav-bar

I am working on a web page displaying a table below a navigation bar. The table on the page is generated from data coming from a database. The page as such does what it is supposed to do, but the table hosting the data is not left aligned on the page, but has a lot of white space to its left.
The Python/Flask-part of the code looks like this, data from the database comes as pandas DataFrame:
from flask import Flask, render_template
import DBConnector
from jinja2 import Environment
import pandas as pd
app = Flask(__name__)
app.jinja_options = {'lstrip_blocks': True, 'trim_blocks': True}
app.create_jinja_environment()
#app.route('/')
def index():
connector = DBConnector()
df: pd.DataFrame = connector.getData()
return render_template('index.html', tables=[df.to_html(classes='data', header=True)])
I borrowed the index.html code from a Stackoverflow post:
{% extends 'base.html' %}
{% block content %}
<h1>{% block title %}Table Viewer{% endblock %}</h1>
{% for table in tables %}
{{ table|safe }}
{% endfor %}
{% endblock %}
which extends the file base.html:

The output looks like this:
How can I remove the large white space to the left of the table?

DataTable not working with Bootstrap 4 in Django

I am new to DJango but have experience with Python. I am creating a Notes Sharing Site. Idea is users will upload notes, admin will accept it and only accepted notes are public. The user can see all of its notes including the pending and rejected ones.
Problem:
Admin is able to see all the users. I am heavily using bootstrap for design because I am trying to focus on back-end. I am using bootstrap tables of viewing the users and viewing the notes ( viewing notes works perfectly because I am not using data table in that table ). Real problem is in viewing users ( by admin ), normal bootstrap table is working perfectly but it is not being modified by data-table. I have not used data able in past it is my first time.
HTML code:
view_users.html
{% extends 'admin_core.html' %}
{% load static %}
{% block head %}
<style>
td {
text-transform: capitalize;
}
</style>

Sorry for spelling mistake ( English is not my first language ) and any noob coding problems. Thanks!
Did you follow the debug or production version for static files? If the debug one then you need the special url paths and if the production one then you need to have STATIC_ROOT path in your settings.py that points to the static directory where the files will be collected with collectstatic command.
Or try Check adding these
import mimetypes
mimetypes.add_type("text/css", ".css", True)

Django Bootstrap Dropdown Menu not working

Building my first Django app from a tutorial, following the instructions pretty much verbatim but my navbar dropdown menu is not working no matter what I try, so unable to log out or change password from the navbar.
I am very new to js, but some things I have tried:
Experimenting w different browsers (doesn't work for Safari or Chrome)
Have looked at similar questions and implemented those techniques but it's still not working (linking to js in the head, making sure to link to js/popper/bootstrap in the correct order, etc.):
django bootstrap dropdown not working
Have also attempted to create static folders in pages/static/js and pages/static/css but that looks like it may be for more advanced styling than what we're going for here.
Bootstrap template not working correctly Django
Template file/directory below. Issue is between lines 55 and 68 (div class="collapse navbar-collapse")
Thanks in advance for the help.

I copied your code and had the same problem but after swapping the bootstrap.js script for a different one it started working.
The problem was a backslash in the bootstraps js URL.
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/\ js/bootstrap.min.js"
integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ\ 6OW/JmZQ5stwEULTy"
crossorigin="anonymous"></script>
After https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/ there is \ js/bootstrap.min.js
but it should be https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js
So when we switched to the newest js it fixed the problem but that js is still valid if you fix the path.

How to fix collapsing navbar that doesn't collapse in Bootstrap

My collapsible navbar is not working on this basic site, and I am not sure why. I have tried to reorder the CDN scripts, copied and pasted directly from Boostrap's docs, and have double checked the code a few times. I'm sure it's a stupid mistake, but can anyone help me and point out what is happening here? The toggle button appears, but doesn't do anything when clicked. This is being used with a Django project.
