I dont know why, but I cannot run the rebuild permissions in post settings. When I select rebuild permissions, it appears to be loading for a second, then goes to the node settings page. No permissions rebuild done.
Also, this may or may not be related, the update.php goes straight to the frontpage when I am at the point of starting the updated of the database.
I use drush to get around issues with slow response and update.php, but do not have a command line work around for rebuilding permissions. Ideas?
