I’m not sure if it was WordPress 2.8, or WP Super Cache 0.9.6.1 that caused this to start happening, but several admin pages on our site are now just a blank white page (including the create or edit post pages!). This is ONLY affecting the admin pages (and not even all of them).

If I turn WP Super Cache to “off”, everything works fine (including the post pages). If I set WPSC back to “on”, the white page of death comes back.

Has anyone else encountered this with WP 2.8 and WPSC 0.9.6.1?
