Using sb-admin-2 styles correctly
It seems that Bootstrap SB Admin 2 are being loaded in Cauldron, but they are not rightly loaded. In the header.html partial/template the file is loaded before Bootstrap css file, so the styles are not applied properly:
<!-- SB Admin 2 styles -->
<link rel="stylesheet" href="{% static 'css/sb-admin-2.min.css' %}">
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
It should be:
<!-- Bootstrap CSS -->
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">
<!-- SB Admin 2 styles -->
<link rel="stylesheet" href="{% static 'css/sb-admin-2.min.css' %}">
Bootstrap CSS file should be the 1st one to be loaded because it's the base CSS for the whole site. The rest of CSS files overwrite or add properties to Bootstrap one
