documentation unavailable in the official site

In all of the official links (9.2, 9.1 etc. up to 8.0) the online general documentation is available, and has links to the user and theory guide https://code-saturne.org/user.pdf and https://code-saturne.org/theory.pdf (the same links for all versions) that point to nothing (error 404).

Not sure how to report this issue and if the github is the right place but I thought it was worthy of mentionning. I will try to download the sources and make doc to see if this solves my issue at least.
