error popup in django not visible

1. Ensure that the Django messages framework is properly integrated into your project.

2. Verify that the necessary middleware is included in your MIDDLEWARE setting in the Django project settings.

MIDDLEWARE = [
    # ...
    'django.contrib.messages.middleware.MessageMiddleware',
    # ...
]

1. Confirm that the django.contrib.messages app is added to the INSTALLED_APPS setting.

INSTALLED_APPS = [
    # ...
    'django.contrib.messages',
    # ...
]

1. Include the messages template tag in your base template to render messages.

{% if messages %}
  <ul class="messages">
    {% for message in messages %}
      <li{% if message.tags %} class="{{ message.tags }}"{% endif %}>{{ message }}</li>
    {% endfor %}
  </ul>
{% endif %}

1. Make sure that you are using the {% load messages %} tag at the top of your template.

{% extends 'base.html' %}

{% load messages %}

<!-- Your template content here -->

1. Confirm that the django.contrib.messages context processor is included in the context_processors setting.

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # ...
                'django.contrib.messages.context_processors.messages',
                # ...
            ],
        },
    },
]

1. Ensure that your views are using the messages framework to add messages.

from django.contrib import messages

def my_view(request):
    # Your view logic here
    messages.success(request, 'Success message.')
    return render(request, 'my_template.html')

1. Confirm that your template is inheriting from the base template that includes the messages template tag.

2. Check for any CSS styles that might be affecting the visibility of the messages. Ensure that the styles for the message tags are appropriately defined.

3. If the issue persists, inspect the HTML source code generated for your page and verify that the messages are being rendered. If they are present but not visible, investigate any potential CSS or JavaScript conflicts.
