Got a problem installing, upgrading or migrating your Moodle site?
Remember to include in your post which version of Moodle (e.g. 2.8.1) you are using!
(You can find your Moodle version via Settings > Site administration > Notifications.)
Also provide as much relevant background information as you can about the versions and configuration of your server OS, PHP and browser.
(including upgrading and migration help)
