WordPress MU

I was making some changes to my version of WPMU 2.7 and have managed to change the link on the Dashboard menu to http://mmow.biz.local/wp-admin/admin.php?page=index.php.

I'm not exactly sure what I changed, as it could be one of many.

my wp-admin/menu.php is unchanged and links and links to index.php

$menu[0] = array( __('Dashboard'), 'read', 'index.php', '', 'menu-top', 'menu-dashboard', 'div' );

Anyone have any suggestions on what to check?

Cheers

My bet would be comparing your files to clean WPMU's files :)

Don't use files named index.php in your plugins subdirectories:

Among others.

I don't believe the wp.org fix has been applied yet.

edit: And if you have index.php files in either plugin subdirectory, they need to be removed:
