Support for Drupal 7 is ending on 5 January 2025—it’s time to migrate to Drupal 10! Learn about the many benefits of Drupal 10 and find migration tools in our resource center.
subsites_form_alter_block_visibility() builds up its $form visibility settings under page_vis_settings, which is the D6 way. I'm still puzzling through D7 examples to suggest changes. Furthermore, *I think* $delta isn't being set somewhere and Block Classes (http://drupal.org/project/block_class) is expecting it to (Block Class not working for blocks with no delta values) but I may be wrong.
Yes, I know, Subsites D7 isn't even "officially" dev yet, but I do hope to do my part to push this along.
