Anytime I go into Site Building, I get: * warning: Invalid argument supplied for foreach() in /www/****/****/drupal/modules/block/block.admin.inc on line 33. * warning: Invalid argument supplied for foreach() in /www/****/****/drupal/modules/block/block.admin.inc on line 52. * warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'block_admin_display' was given in /www/****/****/drupal/includes/menu.inc on line 348. And if I try to load the Block page, it's simply a mostly blank white page, with: Block Region Weight Operations At the top, in bold, and nothing else. I've looked into block.admin.inc, and I don't see anything odd/weird, but I'm certainly no expert. This is preventing me from moving our amateur radio club's new site to "live" status. Any ideas?
