I've started having problems with drupal CVS. When I add a new story, blog or forum page, I get something like the following:
user error: Duplicate entry '3' for key 1
query: INSERT INTO node (title, body, uid, created, type, status, promote, moderate, static, comment, teaser, changed, nid) VALUES ('forum topic', 'this is another forum topic', '1', '1053092880', 'forum', '1', '0', '0', '0', '2', 'this is another forum topic', '1053092898', '3') in /home/sites/site88/web/drupal/includes/database.mysql.inc on line 75.
