KeyError: 'scoreboard.listing_3d' when accessing /challenges

[Sl4cK0TH]

Hello,

I am trying to use the WMCTF 2025 theme with CTFd, but I encountered an error when attempting to log in and access /challenges. The homepage loads correctly, but navigating to other routes causes a server error (500).

It looks like the theme is referencing a non-existent endpoint: scoreboard.listing_3d.

---

Steps to Reproduce:

1. Install CTFd (latest version with Python 3.11).

2. Clone and build the WMCTF 2025 theme based on the Installation Procedure in the Repo.

3. Edit the theme to ctfd-wmctf2025-theme in the CTFd platform.

4. Log in and navigate to /challenges.

Expected Result:
Challenges page should load normally.

Actual Result:
500 Internal Server Error.
