Admin Footer Text Issue - Please Help!


I have a strange issue. I get an error message whenever I try to save the Super Admin Options page. In get:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'admin_footer_text_site_admin_options_process' not found or invalid function name in /home/********/public_html/wp-includes/plugin.php on line 395

Warning: Cannot modify header information - headers already sent by (output started at /home/********/public_html/wp-includes/plugin.php:395) in /home/sarahssu/public_html/wp-includes/pluggable.php on line 890

I am running 3.0.4, with the latest version of Admin Footer Text installed as instructed (in plugins, network activated). Admin Footer Text does show up as its own separate menu under Super Admin.

Any help will be appreciated.
