The node_access Table

I'm starting to gather knowledge on how the ACL Drupal module works.

On a fresh install, the node_access table contains one entry:

This entry grants view access to all nodes. When you install an access module, this entry is replaced by module-specific node access entries.

Access Denied to Anonymous Users

When you subsequently remove the access module, your node_access table is typically left with entries like

(one entry for each of your nodes). These entries grant View access to all of your existing nodes, but any subsequently created nodes won't be visible when you create a new node, because they don't get that entry.

To fix this problem, click on [Rebuild permissions] on admin/content/node-settings; this will put back the default record shown above.

P.S. Here's a character-only template for cut&paste:

+-----+-----+---------------+------------+--------------+--------------+
| nid | gid | realm         | grant_view | grant_update | grant_delete |
+-----+-----+---------------+------------+--------------+--------------+
|   0 |   0 | all           |          1 |            0 |            0 |
+-----+-----+---------------+------------+--------------+--------------+
