# System Information

The information is displayed in a tabbed format with three main sections of content.

System Info Tab: This a broad snapshot of the server and versions of the current installation components of your Mambo site. Here you will find your PHP build and version, your MySQL database version along with the Mambo version and relevant settings that your server has set that might interfere with your current site installation. Here, you will also find the contents of your Mambo Configuration file. This file is produced when you perform the installation of Mambo on your server, and is changed when you make changes to in the global configuration section of the Administration of Mambo. This file defines many of the global variables that Mambo uses to execute. You can not edit the file from here, but it does allow you to look at your current settings to find problems or to copy the information for a support post on the forum on www.mamboserver.com.
PHP Info Tab: PHP is the server side scripting language that Mambo runs on. This language is installed and executes on the server, and therefore all the settings are made on that server. Everything you ever wanted to know about the PHP installation on your Mambo server is listed here. How much control you have over changing this information depends on whether you own the server or if your server host is willing to work with you on needed changes. The PHP tab will allow you to look at all the settings and variables that define your PHP installation. It is a good practice to insure that you know what requirements are needed for any 'Third Party' Components that you plan to use with Mambo. You can then check for those requirements here.
Permissions Tab: Displays a list of all critical Mambo directories that should be writable in order for Mambo to function correctly. If you find a directory that is not writable, you should change it to writable. You cannot do it from here. You have to do it using your FTP client, or asking your hoster to do it for you.
