@XiNaru You'll be happy to know that DefaultRevamp will include a dark theme in pr9!
If you want to try out NamelessMC, use one of these demo websites:
Click through the installer and set up an admin account. If a website has already been installed, please try a different demo link. The demo sites are reset periodically.
For the development version, we highly appreciate bugs and feedback on our GitHub issue tracker.
If you are okay with spending money, why not pay someone else do host the server and do the installation for you? https://namelesshosting.com by Partydragen and https://namedhosting.com by me provide this experience.
Or, if you still want to host it yourself, I'd recommend using our docker images for easy setup.
If this is not about webserver setup, please provide more information about your issues as cpk said as well
