After installing the plugin in the Network Admin Panel there is no plugin menu or options.
After google research I've been able to recover the menu changing "admin_menu" to "network_admin_menu" in the welcome-pack-core.php
But when I click on Save Settings I'm redirected to a blank page, in the URL .../wp-admin/network/options.php. My settings are not saved.
I tried then in welcome-pack-admin changing the form action from "options.php" to "../options.php" but then I receive a WordPress message "This page doesn't exist".
It's a clean installation of WP 3.1, Buddypress 1.2.8 and only those Plugins: Akismet, Google XML Sitemaps and W3 Total Cache.
