Version 1.7.19: Probleme

Hi –
I got problems with the new version of adminimize. Role: editor, pages and edit page:
Undefined index: editor in ../adminimize.php on line 1122
Any ideas?
I know next to nothing about php – this seems to be the relvant function:
foreach ( $user_roles as $role ) {
$user = wp_get_current_user();
if ( is_array( $user->roles) && in_array( $role, $user->roles) ) {
(line 1122) if ( current_user_can( $role ) && is_array( $disabled_metaboxes_page_[$role] ) ) {
$metaboxes = implode( ‘,’, $disabled_metaboxes_page_[$role] );

Thanks a lot for your help!
Greetings
Barbara

I resolved this one but thought I might as well list it: mediathek/media library: ../query.php on line 2390 – with the help of this code (might be connected with php version)
