Sitemap file size error

[dmitri]

After running sitemap generator, creating sitemaps (sitemap.xml; sitemap1.xml; sitemap2.xml) and submitting sitemap to Google recieved an error message in Google webmaster panel:

Sitemap file size error
Your Sitemap exceeds the maximum file size limit. Please create multiple Sitemaps containing fewer URLs to meet the file size limit.

Yes, sitemap1.xml has filesize 11,769,370
How to do it smaller?

Any idea or support?

Hello,

please decrease the number of URLs per sitemap file manually in config.inc.php file:

Code:

    'xs_sm_size' => '30000',

(default is 50,000) and regenerate sitemap.
