This is an error I get when I try to run the SiteMap

Database error in vBulletin 3.6.8:

Invalid SQL:

SELECT *
FROM vbulletin_thread AS thread
WHERE forumid = 51
AND visible = 1
AND pollid > 0;

MySQL Error : MySQL server has gone away
Error Number : 2006

I just hit the "Run NOW" button in the Scheduled Events section.

Thanks.

Hello,

you should not execute sitemap generator via scheduled task manager, use vbsei_sitemap/ interface instead.
