[support] Permissions problem: edit page content

Hello,

I have a role called "site developer" that should be able to edit any page, but for some reason they can't. On the access-control page (admin/user/access), this role has the permissions "administer nodes" and "edit page content". So users with this role should be able to edit any page, right?

I am running Drupal 5. Ten minutes ago I deleted everything in the node_access table and inserted the following line:

INSERT INTO {node_access} VALUES (0, 0, 'all', 1, 0, 0)

I have the taxonomy-access module installed, but I'm not using it for page nodes.

Any ideas? Is it safe to run "rebuild-permissions"? I don't want to lose what I just gained by editing the node_access table.

Thanks for the help.

Daniel.
