Problem with wordpress 3: Call to undefined function is_site_admin() and plugin doesn`t work

Hello,

i’m a new one at wpmudev. I’ve installed worpdress 3, enabled multisite, upload correctly update-notifications.php file from rebranding-wordpress-mu, but when i`m trying to login into admin panel i receive an error: “Fatal error: Call to undefined function is_site_admin() in /wp-content/mu-plugins/update-notifications.php on line 417”

Please tell me what is wrong with that file?

The second: uploaded into mu-plugins file login-imagelogin-image.php from “rebranding wordpress” doesn`t work. i mean there is NO additional options into admin panel to change images – why?

regards,

dl

    Hi

    1) You can remove update-notifications.php for now as you don’t need it unless you want notifications of updates – however, can you check that you have the multi-site enabled (have a look in the Tools menu for network) as this function does exist when multi-site is enabled.

    2) Does the instructions tell you to place the login-image directory in mu-plugins or just the file? php files in sub-directories in mu-plugins aren’t run by default unless another file or plugins loads them itself.
