Admin links showing Dashboard, data not visible, in 4.4.6 DB

[anorthite]

Links such as civicrm/admin/setting/url?reset=1 and civicrm/admin/uf/group?reset=1 display the home/dashboard page at civicrm/dashboard?reset=1. Searching the database shows all contacts, and old mailing list reports are visible, but the campaigns dashboard shows none of the surveys or petitions that are in the database. This might have happened after upgrading the database from 4.4.5 to 4.4.6, the 4.4.5 backups are working normally.

Should I attempt to upgrade the 4.4.5 database backup again, or is there a way to fix this? Thanks in advance.

Edit: This is a multi-site install. I just noticed that the two child sites display the admin pages correctly, it is only the site with domain ID 1 that isn't working. I've tried importing the database to a mirrored local install, it has the same problem, so I assume the config files aren't at fault.
