WP Toolbar is Gone


I have Pro Sites and Easy Blogging installed on WPMU.

I can get the WP Toolbar working on all back-end installs on this network.

The buddypress admin bar comes up fine - and I have disabled it by adding:

define( 'BP_DISABLE_ADMIN_BAR', true );

to the wp-config.php

Does anyone know how to force the WP Toolbar on the front end?

- I have used a few user profiles and enabled it on the profile (if the setting is there)
- There is no plugin that seems to be restricting it.
- Easyblogging is set to show it.
- It does not show on multiple themes

Any help would be much appreciated.
