Please, use https://moodle.org/plugins/block_admin_presets instead of moodle flavour to import/export Moodle site settings. You can still use Moodle flavours to pack plugins, language packs and language strings customisations, but it is not recommended for settings.
With this plugin Moodle Administrators will be able to create a flavour from their installation, selecting which settings, plugins and language packs will be packaged into a compressed file. They can then, share the package with the Moodle community, store it as a backup or use it to replicate the flavour to other installations they manages. It could also be useful for administrators with little Moodle experienced, allowing them to explore the Moodle settings and setup recommended by others.
It has been developed as part of Google Summer of Code 2011 and mentored by Michael de Raadt.
Moodle 2.1 or higher required, to install, please, follow the README steps.
