When logged in as a non-site admin on moodle 2.0.6, clicking on "Site Home" redirects directly to "My Home" so the user can never reach "Site Home".
This is caused by the logic in index.php for site home being incorrect.

Currently as :
} else if ($CFG->defaulthomepage == HOMEPAGE_MY && (optional_param('redirect', true, PARAM_BOOL) || !$hassiteconfig))

{ redirect($CFG->wwwroot .'/my/'); Which redirects if the deafault home page is My Home AND either the redirect param is true OR user is not a site admin But this means that non-site admin users cannot reach Site Home. Should be : }

else if ($CFG->defaulthomepage == HOMEPAGE_MY && optional_param('redirect', true, PARAM_BOOL) && !$hassiteconfig) {
redirect($CFG->wwwroot .'/my/');
