We've got an issue with aliases at our www.hybrid.cz website. There's an image gallery at http://www.hybrid.cz/galerie/volkswagen-up The last image has an alias http://www.hybrid.cz/obrazky/volkswagen-up - but it's not working. The alias points to this address http://www.hybrid.cz/node/1656 - which surprisingly works. Tried to delete and create new, even directly in DB, but nothing helps. Our Drupal version is 5.16. Any ideas except for updating Drupal to the latest version?
