The screenshot you shared is from your actual application rather than the admin. We can see from the network tab that the static assets like
boostrap.min.css are loading (and that the page contains some bootstrap styles). Can you share a similar screenshot from the
/admin/login/ page where the static assets do not appear to be loading?
Also, can you list what you have in
INSTALLED_APPS in your settings file?
By the way, for sharing code on the forum, instead of using a screenshot, you can use the backtick (`) character when you put in code. This is sometimes called “fenced code” because 3 backtick characters are used above and below the code and make something that seems like a fence (note: not apostrophe characters!).
This is an example of what that would look like. I had to add extra indentation for this example or else it would come out wrong in the forum. More documentation about this feature is at: https://meta.discourse.org/t/how-do-i-select-a-language-in-code-blocks/19247
