Troubleshooting

Server doesn't fetch resources (missing CSS, JS, images, thumbnails)

In release mode (Debug=False), Django stops fetching static and media resources, the responsibility now falls upon the web server (e.g. Apache, Nginx) to fetch these files. If you are using a web server, you have to map the /static URLs to the folder app/YtManagerApp/static, and the /media URL to the folder data/media. An example is provided for Nginx (under /docker/nginx/nginx.conf).

If you are only using manage.py runserver, you can force Django to fetch the resource files, by passing the --insecure argument (i.e. manage.py runserver --insecure), or simply set Debug=True in config/config.ini.

Videos are not downloaded

A possible issue is that YouTube changed its layout, breaking the currently installed version of youtube-dl. Try to upgrade youtube-dl, by running pip install --upgrade youtube-dl (pip3 on Ubuntu) in a command prompt.
