Question: I am building a registration form for my django project, and for styling it I am using crispy forms. But, when I run my server and go to my registration page, I see this error:  Internal Server Error: /users/register/ Traceback (most recent call last): File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\backends\django.py", line 61, in render return self.template.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 170, in render return self._render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 162, in _render return self.nodelist.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 938, in render bit = node.render_annotated(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 905, in render_annotated return self.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\loader_tags.py", line 150, in render return compiled_parent._render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 162, in _render return self.nodelist.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 938, in render bit = node.render_annotated(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 905, in render_annotated return self.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\loader_tags.py", line 62, in render result = block.nodelist.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 938, in render bit = node.render_annotated(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 905, in render_annotated return self.render(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 988, in render output = self.filter_expression.resolve(context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\base.py", line 698, in resolve new_obj = func(obj, *arg_vals) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\crispy_forms\templatetags\crispy_forms_filters.py", line 60, in as_crispy_form template = uni_form_template(template_pack) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\crispy_forms\templatetags\crispy_forms_filters.py", line 21, in uni_form_template return get_template("%s/uni_form.html" % template_pack) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\loader.py", line 19, in get_template raise TemplateDoesNotExist(template_name, chain=chain) django.template.exceptions.TemplateDoesNotExist: bootstrap5/uni_form.html The above exception was the direct cause of the following exception: Traceback (most recent call last): File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\core\handlers\base.py", line 179, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\Dell\Desktop\Django\microblog\microblog_project\users\views.py", line 17, in register return render(request, 'users/register.html',context) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\shortcuts.py", line 19, in render content = loader.render_to_string(template_name, context, request, using=using) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\loader.py", line 62, in render_to_string return template.render(context, request) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\backends\django.py", line 63, in render reraise(exc, self.backend) File "C:\Users\Dell\Desktop\Django\microblog\venv\lib\site-packages\django\template\backends\django.py", line 84, in reraise raise new from exc django.template.exceptions.TemplateDoesNotExist: bootstrap5/uni_form.html  This doesn't look like the usual TemplateDoesNotExistError I get. I think this is the error in my crispy form, because if I remove the crispy template tags in my form, everything works fine. Here is my register template: {% extends 'base.html' %} {% load crispy_forms_tags %} {% block title %}Register{% endblock %} {% block content %} <h1>Sign up for a new account</h1> <hr> <form action="" method="post"> {% csrf_token %} {{ form|crispy }} <button type="submit" class="btn btn-sm btn-primary">Register</button> </form> <p> Already have an account? <a href="#">Log in</a> </p> {% endblock %}  And just in case it is required, here is my view function: def register(request): form = RegistrationForm() if request.method == 'POST': form = RegistrationForm(data=request.POST) if form.is_valid(): form.save() return HttpResponse("Successfully Registered!!!") context = { 'form':form, } return render(request, 'users/register.html',context)  I have specefied CRISPY_TEMPLATE_PACK in my settings.py and also added crispy_forms to my INSTALLED_APPS. Where am I going wrong? EDIT: So I did a bit more research on this topic and this error is probably because crispy forms does not support bootstrap 5 yet. So, by changing the bootstrap5 to bootstrap4 in my CRISPY_TEMPLATE_PACK, the error is solved

Answer: Based on the latest crispy form doc, it seems that there is no built-in bootstrap5 for it. Are you sure you are using bootstrap5? Currently, there are only bootstrap, bootstrap3, bootstrap4, and uni-form. You can take a look at your file structure if you even see bootstrap5 folder.
