Regenerating the access tables
After trying to run both Taxonomy Access and Simple Access - and finding that this didn't play well together (drupal 5 is supposed to be able to handle this better) the taxonomy access details were hosed. The actual taxonomies were hidden - but the nodes were displayed.
Thanks to help on the drupal forums - to rebuild this I had to:
- Disable taxonomy access (note - thats disable not uninstall)
- TRUNCATE node_access in the database
- Re-enable taxonomy access
This rebuilt the contents of the node access table and all started playing well together :)
