I am having a problem installing mybb which I have narrowed down to permissions on settings.php. What should the permissions be on this file? If I have settings.php chmod to 666, everything works happily. If I change to 664, I am unable to make any changes to the configuration as admin.

During the installation the files settings.php and config.php have to be chmod to 666 (writable), so PHP can write to them. After the installation, you can chmod config.php back to 755 for extra security, but settings.php needs to remain writable (leave it at 666), and you've experienced the reason for that yourself
