Add Page link disappeared


I’m new to WPMU, running ver 2.8.4a.

Installed several WPMUDEV plugins in the main site. Now, in the child sites, (eg. 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.
