Three things to consider:
follow Bootstrap carousel HTML structure as shown in the docs,
use data-bs-target, data-bs-slide-to, data-bs-slide if you use Bootstrap 5 and
include Bootstrap JS only once (Bootstrap JS bundle or Popper & Bootstrap JS separately, not both).

Need help to figure out why my bootstrap 5.0 carousel isn't working, ty

Can't seem to figure out why my carousel won't switch around when I click the arrows.
Thank you for all the help !

Here you go...
You also need to add Bootstrap JS, not only CSS.
Change href="#testimonial-carousel" to data-bs-target="#testimonial-carousel".
Change data-slide="prev" (Bootstrap 4) to data-bs-slide="prev" (Bootstrap 5) and data-slide="next" (Bootstrap 4) to data-bs-slide="next" (Bootstrap 5).
See the snippet below.

Bootstrap navbar not toggling when clicked

I am using Bootstrap 4 to toggle the collapse of dropdown menu for small screens (sm) in my navbar. But the toggling doesn't work, nothing happens when I click on the toggle button.
I made sure to import all the assets/links in correct order. Can any one see what's wrong?

You have a wrong syntax on datatarget, it should be data-target.
Change this:
datatarget="#collapsibleNavbar"
To this:
data-target="#collapsibleNavbar"
Example:
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

Navbar not collapsing after clicking toggle button. Bootstrap 3 with django

I'm experiencing something strange, while trying out bootstrap with django. I copied the dashboard-example from the bootstrap-page (dashboard-example) into my django-project to play around a little bit. When I try to use the collapse navbar for smaller screen-sizes, the navbar is appearing, when I click the toggle-button. But if I click the toggle-button again, the navbar is not disappearing. I copied the example from bootstrap one-to-one. Why is the toggle-button not working as expected? Here is the generated html-code:
