I have only just joined this list and hope that I can find more support here than seems to be available through the forums at drupal.org.

I installed Drupal (latest version) a few days ago and all went smoothly. The system looks and feels excellent and extremely flexible. My problem started when the I signed up a test registration. As soon as I had done that I ran into a persistent error message in watchdog, each time the cron is run.

The error message is….

Location = cron.php

Error = Duplicate entry '' for key 2 query: INSERT INTO users (created, changed, uid) VALUES ('1131884754', '1131884754', '65') in /mounted-storage/home2/*********/******/includes/database.mysql.inc on line 66.

Line 66 of database.mysql.inc simply tells the program to write an error report, so no assistance there. Removing the member had no effect, and signing other members up does not make it any worse. It simply persists in reporting this same error with each cron run.

I noticed one other report of an identical problem on the drupal forum, but that post was lost in the middle of another discussion and was never responded to.

Although the problem does not appear to interfere with the running of other functions in any way, I would like to know what may be causing it, and repair it anyway.

Hope someone can help.

Thank you
