Just editor content. Same issue when I try to customize a theme, I see the menu options on the left, but no content other than the skeleton of the customize page.
All plugins disabled, no cache… good thought though!
Having the same problem, did as MacManX recommended (re-downloaded wordpress, replaced copies of everything except wp-config.php and /wp-content/, but same results, still not working. Thanks for the hint — any other ideas?
