sitemap dont work

I have the same problem. When I select a post type to exclude from the sitemap, the whole thing stops working and I get a page not found error.

I’m on WordPress 4.1.1 and also have problems with xml-sitemaps. I’ve got this info:

array(22) {
  ["blocking_files"]=>
  array(0) {
  }
  ["ignore_blog_public_warning"]=>
  bool(true)
  ["ignore_meta_description_warning"]=>
  bool(false)
  ["ignore_page_comments"]=>
  bool(false)
  ["ignore_permalink"]=>
  bool(false)
  ["ignore_tour"]=>
  bool(true)
  ["ms_defaults_set"]=>
  bool(false)
  ["theme_description_found"]=>
  string(0) ""
  ["theme_has_description"]=>
  bool(false)
  ["tracking_popup_done"]=>
  bool(true)
  ["version"]=>
  string(5) "2.0.1"
  ["seen_about"]=>
  bool(true)
  ["alexaverify"]=>
  string(0) ""
  ["company_logo"]=>
  string(0) ""
  ["company_name"]=>
  string(0) ""
  ["company_or_person"]=>
  string(0) ""
  ["disableadvanced_meta"]=>
  bool(true)
  ["googleverify"]=>
  string(0) ""
  ["msverify"]=>
  string(0) ""
  ["person_name"]=>
  string(0) ""
  ["yandexverify"]=>
  string(0) ""
  ["yoast_tracking"]=>
  bool(true)
}

i deactivated and activated it again and it works on my problem.

I got this to work by resetting the permalink structure in settings.

Mine also not working and I’ve tried resetting permalinks and deactivating/reactivating. Just getting a blank page which nothing appears on?
