I cannot remove the Google Sitemap field from blog pages. I can remove other fields but the Google Sitemap field will not go away.

      $fields->removeFieldFromTab('Root.Content.GoogleSitemap', 'Priority'); 
      $fields->removeFieldFromTab('Root.Content', 'GoogleSitemap'); 

Can anybody else make it go away?

I use:

$fields->removeFieldFromTab('Root.Content','GoogleSitemap');

to remove the tab completely.

Edit: I know you said this didn't work, but that is what i use in my Page.php getCMSFields() to remove the tab. Maybe try again?

Thanks for your reply. I tried that exact code in both Page.php and BlogEntry.php and while I can successfully remove all other fields and tabs, the Google Sitemap Field does not go away.

Try this:

$fields->removeByName("GoogleSitemap");
