I'm running WP 2.5 and just upgraded Sitemaps to 3.1.2 by uploading it to the server.
When I go to Settings/XML-Sitemap I'm getting a fatal error in the "excluded Items" section:
Note: Using this feature will increase build time and memory usage!
Fatal error: Call to undefined function wp_category_checklist() in /home/scamout/public_html/blog/wp-content/plugins/google-sitemap-generator/sitemap-ui.php on line 999
Output is dying at that point and I cannot save any settings because the SAVE button isn't there.
It appears that a valid sitemap is being generated.
Any ideas about what's up?
