[Django]-Invalid block tag : 'endblock'. Did you forget to register or load this tag?

✅

Django didn’t recognise your starting block tag, because you have a space between the { and the %.

You also have the same error in both start and end tags in the other template file.

You simply have typos.

You should have {% not { %, and you got those typos in both of templates.

So you need to have 

<!DOCTYPE html>
<html lang="en">

  <head>
    <meta charset="UTF-8">
    <title>{% block title %}{% endblock %}</title>
  </head>
  <body>
    {% block content %}   {% endblock %}
  </body>
</html>

and 

{% extends "layout/layout1.html"%}


{% block title %}The Video page{% endblock %}


{% block content %}
  <h1>This is a html</h1>

  <p>This is a p tag</p>

  <a href="http://www.noobmovies.com">Click me!</a>
  <img src="https://upload.wikimedia.org/wikipedia/en/7/72/Anthony_Raneri.jpg"/>

{% endblock %}

NOTE: don’t forget about identations in html files, it makes code more readable.

If none of the previous answers worked for you, try the following:

You are most likely using a base.html file and have the static css being loaded on the top {% load static %} and the problem for me was that I needed to also load this in my other template file.

I’m using Django 2.0.3 and this solved the issue for me.

For me it was emacs breaking the lines up when I copied the template over, so 

{% endif

was on one line and 

%}

was on the next line. These need to be together on one line, and 

{{ variable_name }}

too.

in my case use {% load static %} after {% extends 'base.html' %} solved.

I got this error because I mixed up {% %} and {{ }}. I had:

<title>{% user.name %} ({% user.id %})</title>

When I should have had:

<title>{{ user.name }} ({{ user.id }})</title>

For me it was the issue of using i18n without putting the {% load i18n %} inside the template file (I only put it in the base template)

For me the problem was with {% extends %}, it was extend.

In your Html template, ensure you {% load static %} just after your {% block content %}
before using it in the template

In my case,
{% csrf token %} instead of this {% csrf_token %} solved.

If you are missed _ (underscore) in code then also you will got this error.

Similar to @gal-bracha answer, for me the problem was caused by including a template inside another (through the {% include %} tag) and both templates making use of a {% trans "some text" %} tag. In this case, the {% load i18n %} must be written in both the including and in the included templates.

Not to answer this specific question, but to share my case which gave the same error:
In my case this same error been caused because I forgot to add the url in the link reference name:

href="{% url 'allblogs' %}".  worked.

while error was received when url was missed like below:

href="{% 'allblogs' %}". Error been generated.

if you encounter this:
Invalid block tag on line 172: ‘endfor’. Did you forget to register or load this tag?
Check:
Any part of your code commented, check if {% endfor %} has been repeated.
If it is repeated delete one especially the commented section.
Thank you.

in my case i used replaced {% csrf token %} with {% csrf_token %} and it seemed to work.

In any template that uses a POST form, use the csrf_token tag inside the <form> element if the form is for an internal URL, e.g.:

<form method="post">{% csrf_token %}

This should not be done for POST forms that target external URLs, since that would cause the CSRF token to be leaked, leading to a vulnerability.

This also happens when you forget putting your phrase between quotes.

{% trans My phrase %}

instead of

{% trans "My phrase" %}

Apparently even double space between {% endblock and content %} is also a problem in version 4.1.7
Corrected to a single space and it worked fine.i.e:

{% endblock  content %} # failed. Note the double space
{% endblock content %} # worked fine
