At some stage yesterday, when clicking Configuration Drupal 7 would revert from Overlay to /admin/config and the page was blank (Page Source too). I could get to other admin pages like /admin/config/search by typing in the URL. Just the Configuration page will not appear.
I did a clean install of D7 just now. Added all the modules I needed individually and check I could see all page. After I added the Token module the problem appeared again.

Project:Token» XML sitemap
Version:7.x-1.0-beta1» 7.x-2.0-beta1

The problem was found when I added XML Sitemap module. One check box. Not Token sorry.

There's a WSOD bug with the current beta1 release. Try out 7.x-2.x-dev, which is fully supported via the upgrade path.

Same happens with the dev version of this module.
Enabling this module makes the admin/config page go blank.

Same bug last fortnight

If display_errors=on, /admin/config prints:

Fatal error: Call to undefined function file_directory_path() in /home/***/public_html/sites/all/modules/xmlsitemap/xmlsitemap.module on line 975

7.x-2.0-beta1

Shouldn't You use file_default_scheme() . ':/' ??
