Site map generated more then once

Hi, in my forum the sitemap is generated more than once

In the scheduled task i have:

vBSEO - Create Google/Bing Sitemap (time 01:00)
and
vBSEO Search Engine XML Sitemap (time 02:00)

i receive the email that sitemap is generated from 01:00 to 02:00, total 40 email

the .htaccess
#RewriteCond %{HTTP_HOST} !^www\.yourdomain\.com
#RewriteRule (.*) http://www.yourdomain.com/forums/$1 [L,R=301]

RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron|vbseo_sitemap|api\.php)
RewriteRule ^((archive/)?(.*\.php(/.*)?))$ vbseo.php [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

Check your scheduled tasks manager.

You likely have 2 tasks there.

Delete both, then re-import the vbseo sitemap product file, which will re-create the correct task.
