Forum Database Error During Upgrade
 

Hello,

I created a copy of my database so I can perform an upgrade on my test forum.

On step 3 of the upgrade I'm getting this error:

Code:
Database error in vBulletin 3.8.4:

Invalid SQL:
INSERT INTO vb3_cron
(nextrun, weekday, day, hour, minute, filename, loglevel, varname, volatile, product)
VALUES
(1232082000, -1, -1, 5, 'a:1:{i:0;i:0;}', './includes/cron/sitemap.php', 1, 'sitemap', 1, 'vbulletin');

MySQL Error : Duplicate entry 'sitemap' for key 2
