Shonu on "[Plugin: User Activation Keys] Install and approve Errors on Network WP"

Hi

when I approve a user, I get this ugly page:

Warning: Creating default object from empty value in 

*/wpcms/wp-includes/ms-settings.php on line 111
Your account is now active!
Username: blahblah
Password: hqgAtm4nhX2n

Your account is now activated. Log in or go back to the homepage.

is that normal? A nice fancybox would be better. But it worked still.

When I installed, I got:

Warning: fileperms(): stat failed for 

.../public_html/wpcms/index.php in .../public_html/wpcms/wp-admin/includes/file.php on line 871

Thanks
