A long time ago I created a special content type called Ad in my Drupal 6 website with 1 difference from a standard Page: an Ad can be scheduled (drupal.org/project/scheduler). I've created a view that shows all Ads in chronological order. Ads are set to unpublish 6 months after they are created (manual entry in the unpublish field). All this has worked fine.
After the migration to Drupal 7 I noticed that in a view the title and body are displayed, but in single node view I get a white screen. After checking the Drupal 6 version, it has the same problem.
Editing is ok, but I cannot get the node to display on a single page.
I've tried to find errors, but there are none. There is no mention of memory problems.
I have no idea how to find out how to fix this problem.
Update: it happens only when logged in, the anonymous user can see the single node view correctly.
Another update: looks like the problem lies in the pathauto alias. This is what I did: I changed the type of the node to 'story' by manually changing the MySQL records. Still a white page. Then I changed the url alias in the database to something that matches a pathauto url for a story. Voila, the page displays.
But what's wrong I don't know.
