I can't edit my theme files from the WP admin UI. When I go to Presentation > Theme Editor, style.css is automatically selected as it's at the top of the list. When I choose one of the other files on the right to edit, it doesn't switch files; instead, it just pulls up the same style.css file even though the URL is changing to indicate that the file should be changing too (http://deanish.com/wp-admin/theme-editor.php?file=wp-content/themes/MistyLook/footer.php&theme=MistyLook should pull footer.php but still pulls up style.css). I encounter this problem across all themes. Any ideas?
