What are the system requirements?
The self-service / download version of CCM19 only requires PHP 8.2 or higher and the mod_rewrite module on your LAMP server in order to function. NGINX is also possible - a configuration file is included in the download. Further information on NGINX can be found here: https://www.docs.ccm19.de/api/technik/#nginx
The service tariffs only require the possibility to integrate a Javascript into your site - an installation is not necessary!
