If any of these items are highlighted in red then please take actions to correct them. Failure to do so could lead to your Mambo installation not functioning correctly.
These settings are recommended for PHP in order to ensure full compatibility with Mambo. However, Mambo will still operate if your settings do not quite match the recommended.
In order for Mambo to function correctly it needs to be able to access or write to certain files or directories. If you see "Unwriteable" you need to change the permissions on the file or directory to allow Mambo to write to it.
