Hello, I do have some Drupal 6.0rc4 issues, maybe those are known. My setup: Drupal 6.0rc4, postgresql 8.1.11, php 5.2.5 and currently the fckeditor module as the only addon.
My first problem:
1) How do I clear a somehow corrupted database? I have a book site, which, after editing and trying to save, created an sql error. Now, this site is gone, but the link is still there.
Even as superuser, under content administsration, when trying to delete this link, I reappears under content - and no logentry is made. However, the node it refers to, is nonexistant.
Further, I cannot create any new content anymore, as I will get an sql error upon saving - see below.
After deleteing the parents of this bookpage, my frontpage became inaccessible (Access Denied). However, this book was never promoted to front page, albeit book navigation was available to anonymous users. Login is still possible, though.
An example error after trying to create a page:
* warning: pg_query() [function.pg-query]: Query failed: FEHLER: duplizierter Schlüssel verletzt Unique-Constraint »node_vid_key« in /home/www/htdocs/cms/includes/database.pgsql.inc on line 138.
