Hello,
The installation is unfortunately failing here: https://paste.yunohost.org/raw/izoxojicug
EDIT:
I made the install work by:
- keeping only one “#” in front of “replication” in
/etc/mongodb.conf(uninstall keeps adding additional ones) - executing
apt remove mongo*beforehands
And now… how do I create a user? 
Subscription seems blocked (advises to send an email to the administrator)
EDIT2: OK, figured out when going in the Yunohost app admin section → https://domain/launchpad
EDIT3:
Sending e-mail doesn’t seem to work (“Something went wrong. Please try again.”)

Document PDF generation doesn’t work (" Erreur de rendu PDF
Une erreur s’est produite lors du rendu de ce PDF. Please try recompiling the project from scratch, and if that doesn’t help, follow our troubleshooting guide.")
I can’t download the log files either (error 404).
EDIT4:
Found out it was caused by the fact that my /home/yunohost.app is a symlink, and the apps forbids it. Setting directly the direct path in the settings.js file did the trick.
