Add Page link disappeared

Hi:

I’m new to WPMU, running ver 2.8.4a.

Installed several WPMUDEV plugins in the main site. Now, in the child sites, (eg. domain.com/site1/) under Pages, the Add page link disappeared.

It is only visible if I log in with the main site password.

Any clues of what I did or which plugin needs setup?

Before installing several plugins (don’t remember which ones) everything was working fine.

Thanks.
