Hi Amaia,
There may be a usability problem with the upgrade and the cron setting. If a system is installed or upgraded the cron will not run immediately, but defaults to running on the first day of the month. If some upgrades today, they may may have to wait thirty days they can user H5P unless they manually run the script. It seems like there should be a setting that prompts the admin whether the script should be run immediately when upgrading.
