Undefined variable

I too am getting this error and more, even after disabling and uninstalling the module (not removed from server files though).

Notice: Undefined index: comment_node_family_individual in _field_ui_bundle_admin_path() (line 325 of /home/drupal/public_html/modules/field_ui/field_ui.module).
Notice: Undefined index: comment_node_family_individual in field_ui_fields_list() (line 35 of /home/drupal/public_html/modules/field_ui/field_ui.admin.inc).

So there are still remnants left in the system somewhere and are impossible to get rid of.

I receive the same error after enabling the module for the first time.

Notice: Undefined variable: block in family_block_view() (line 319 of /home/proots/public_html/sites/all/modules/family/family.module).

Fixed in new release.
