Directory and File Permissions:

In order for TWG 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 TWG to write to it. Please check how-to 1 on the web site for good security settings!

Recommended settings:

These settings are recommended for PHP in order to ensure full compatibility with TWG.
However, TWG will still operate if your settings do not quite match the recommended
