hi drupal community,
i have to deal with a very strange "page not found" error.
a site i set up for a vocational institution returns "page not found" on any request for a node.
the site still allows to create new nodes and shows them as it should.
when examining the database with phpmyadmin i run into another strange phenomenon:
the list of nodes shows correctly but when i try to go on the edit view of a specific dataset in the node-table, phpmyadmin returns an empty result - as it does when i run a mysql-query for a certain node, e.g. using the nid as parameter like this: SELECT * FROM `node` WHERE `nid`=1 ... returns empty result while this very node is shown on the phpmyadmin-page that lists the content of the node-table, showing title, timestamp, nid, a portion of teaser and body etc. of every node.
surprisingly i managed to have the site show its nodes again by copying the database and changing settings.php to connect to the copy with exact the same content as database no.1.
the site is run on a very old drupal version (no changelog.txt on the server, index.php´s is dated with august 2004).
i already emptied cache following the results of research on drupal-forums but cache wasn´t activated anyway.
