Missing argument 2 on wp-super-edit-core.class.php ERROR MESSAGE

Any idea what this means and what I should do about it? I've updated everything, but the error message still appears.

Warning: Missing argument 2 for wpdb::prepare(), called in /home/hammtest/public_html/wp-content/plugins/wp-super-edit/wp-super-edit.core.class.php on line 114 and defined in /home/hammtest/public_html/wp-includes/wp-db.php on line 990 Warning: Cannot modify header information - headers already sent by (output started at /home/hammtest/public_html/wp-includes/wp-db.php:990) in /home/hammtest/public_html/wp-includes/option.php on line 568 Warning: Cannot modify header information - headers already sent by (output started at /home/hammtest/public_html/wp-includes/wp-db.php:990) in /home/hammtest/public_html/wp-includes/option.php on line 569
