Err... 50k pages... Now what?

[me11]

So my site has just around 50,000 pages to index. Google's Webmaster Tools is telling me that my sitemap has TOO MANY URL's to add to it's database, even though I haven't run the generator since it was at ~ 40,000 pages (39,491). Why would google say it's too many? How can I make the generator make only 20,000 URL's per XML file?

Hello,

Google allows up to 50,000 URLs *per sitemap file*.
You can decrease the number though in generator/config.inc.php file:
'xs_sm_size' => '20000',

and regenerate sitemap.
Make sure that you create sitemap1.xml, sitemap2.xml etc files in domain root and set 0666 permissions for them so that sitemap generator can store multifiles sitemap.
