Hai man,
I dont know about about wpmu but am using wp 2.7
and i was having a problem with logout...
When user clicks on logout its get redireted to the home page but user is still logged in...
It displays the msg
"You Attempting to logout of the siteurl
Please try again"
where please try again is a hyperlink and when the user clickc it just redirection to the home page occurs without loggingout....
However I was able resolve this using the following steps...
1)My logout links comes from a plugin called
"usersidebarpanel"
the path to it seems something like
"wp-content\plugins\usersidebarpanel"
2)Inside usersidebarpanel there is a file called as
"functions.php"
3)edit this file as follows
In this page somewhere about lines 61,93,100
there is a piece of code as given below
echo '<li><a href="'.get_bloginfo('wpurl').'/wp-login.php?action=logout&redirect_to='.get_option('siteurl').'" title="'.$usp_language['logout'].'" >'.$usp_language['logout'].'</a></li>';
4)Replace This code with the following code given below
echo '<li><a href="'.wp_logout_url(get_permalink()).'" title="'.$usp_language['logout'].'" >'.$usp_language['logout'].'</a></li>';
5)Thats it and check out...
