CMSimple_XH is designed to run on almost every internet server. The server- and client-side requirements for installing, administrating and running CMSimple_XH are listed in the following sections.
CMSimple_XH requires PHP 4.3.10 or higher (successfully tested up to 5.6.5). At least PHP 5 is recommended, though; if the server is running PHP 4, you can probably switch to PHP 5 in the wespace's control panel. The PHP extensions “date”, “pcre”, “session” and “xml” have to be installed, what's normally the case everywhere.
No database is required, as all data are stored in flat files.
An Apache HTTP server is recommended, but CMSimple_XH should also run on other servers (successfully tested with IIS and NGINX).
Some extensions might have more demanding requirements, for example some plugins require PHP 5 to function properly. This should be mentioned in the dokumentation of the respective extensions.
