Showing an error CSS error.

Hi there, I have installed your theme on CTFd platfrom 2.4.2
It is showing KeyError: 'views.custom_css' while changing theme.

Base.html
Line no 26
<link rel="stylesheet" type="text/css" href="{{ url_for('views.custom_css') }}">

We were using 2.2.0 or 2.1.5, major theme change where mad on CTFd at 2.3.0 and 2.4.0.

It seems it is https://github.com/CTFd/CTFd/releases/tag/2.3.0 that breaks it.
