When doing a multilingual quarto website using profiles (240619-1425 Quarto multilanguage website), quarto preview/render --profile de allows previewing only one language, and the menu links (/de/xxx) break.

Solution to preview EVERYTHING, including menu links logic:

# Todo break on erorr
quarto render --profile=ua
quarto render --profile=en
quarto render --profile=de

And then serve the _site directory locally through a simple webserver, e.g. Python SimpleHTTPServer - Python HTTP Server | DigitalOcean, and see the result on http://localhost:9000:

python3 -m http.server -d _site 9000
