This page guides you through an upgrade of CONTENIDO from CONTENIDO 4.8 to 4.9. For an installation, please have a look at this guide.
Since CONTENIDO version 4.9.13 10 you have to set chmod permission 755 instead of 777. PHP must access the files as owner. Please respect also the owner permissions (chown) for your directories.
If you changed configurations for the backend, you must apply them to the new configuration files in data/config/ENVIRONMENT. We recommend you to use the config.local.php, so you don't have to modify any core files.
Cleaning up and finish upgrade
This is only relevant if you use CONTENIDO version 4.9.13 10 or newer
CONTENIDO configures automaticly "SMTP" as transport type for your mails. But before it works, you have to configure the login informations at backend. Please go to the menu item "System" and "Configuration" to configure your SMTP mail server. If you do not want to use SMTP as mail transport type, you can choose alternatively "PHP mail".
