Anonymous/public access to group content not working

I'm using drupal 4.6.5 on remotely-hosted unix/php (v4.4.1)/mysql (v4.0.25)

I just updated to og.module version: 1.53.2.32 2006/01/19 06:15:42

I also updated the og_uid table, confirming addition of the three new fields, and ran update-og.php.

I have checked the Public box on the node pages, and access control has all node content viewable by anonymous users.

I want all the content in all of the groups to be viewable by anonymous, so I tried both of the following options on the og groups settings:

Visible within the targeted channels and on other pages
Visibility chosen by author/editor using a checkbox on the posting form. Checkbox defaults to Public.

It seems no matter what I do I cannot make any group content viewable to anonymous users.
