Hi, $PMA_List_Database->items is built in common.lib.php at the beginning. I just added in db_operations.php a call to rebuild it $GLOBALS['PMA_List_Database']->build(); because for the db rename operation, we create the new db but it's not present in the list. Later, the logic checks for existence of the target db via if (! $GLOBALS['PMA_List_Database']->exists($source_db, $target_db)) { and it failed. Now I wonder if we should rebuild the list more often, for example when a db is created or dropped. Marc
