Upgrade to Drupal 6.4 broke site... :-(

Having moved this site from static HTML to Drupal 5.7 a few months ago, it now seems all the add-ons I want are available for Drupal 6. So I upgraded.

OUCH! Broken menus. Visitors lost everything except the Contact link. Since the site is quite small, it seems likely the only unusual thing is a lot of content that remain as .htm files, outside Drupal. Thank goodness for the backup I took immediately before the upgrade... I've given up investigating the problem and returned to 5.7.

It's a big disappointment, because even during the short time I used 6.4 I could see worthwhile improvements.
