Does this site look broken?. Use the LitterTray web for test cases.

When a topic in the cache needs to be updated the onReload() handler is called but the _onReload() method is to be called instead which then calls the onReload() method (mind the underscore). The _onReload() handler is the default handler of the DBCacheContrib::WebDB base class that grants that a minimun stuff is done in any case...like setting the _up relation. So the _up relation was set only the first time the cache was created but not when a topic in it needed to be updated (using _updateCache() ) .

A one-char fix:

--- lib/TWiki/Contrib/DBCacheContrib.pm (revision 8675)
+++ lib/TWiki/Contrib/DBCacheContrib.pm (working copy)
@@ -378,7 +378,7 @@

     if ( $readFromFile || $removed ) {
         # refresh relations
-        $this->onReload( \@readTopic );
+        $this->_onReload( \@readTopic );
     }

     return ( $readFromCache, $readFromFile, $removed );

Fixed in SVN 8682.
