message="
Kresus was updated!
Domain: $domain
Path : $path_url
Config: $final_path/config.ini
Please remember the default behavior of YunoHost when installing a new app is: everyone has access to the app.
This may be an issue for Kresus as it is a personal tool. Please remember to edit access rights in the YunoHost web administration panel or using command line interface.
Note about config.ini: this package will regenerate the config file on upgrade.
If you changed it manually and upgrade Kresus, you'll find a backup in $final_path.
Are you facing an issue, want to improve this app or say thank you?
Please open a new issue in this project: https://github.com/YunoHost-Apps/kresus_ynh
