WordPress MU

I can't do any change in my blog. When I tray saving the changes it appears a message that says "No admin" what can i do? Please help me!

Thank you

Where in your blog exacly ?

i do'nt know what's your problem exactly you may need to update user role from / User / Autor & users on your admin area ..
if dosen't help

edit /wp-admin/options.php

fint this lines:

if( $option_page == 'options' ) {
		if( is_site_admin() ) {
			$options = explode(',', stripslashes( $_POST[ 'page_options' ] ));
		} else {
			die( 'Not admin' );
		}
	} else {

Replace with:

if( $option_page == 'options' ) {
		if( is_site_admin() ) {
			$options = explode(',', stripslashes( $_POST[ 'page_options' ] ));

		}
	} else {

Find this lines:

default:
	if (!is_site_admin())
		die('Not admin');

	include('admin-header.php'); ?>

Rplace with:

default:
	if (!is_site_admin())
		die('Not admin');

	include('admin-header.php'); ?>

But It's not Safe !!!
