Hi Visayafan,

This variable no longer exists, since quite I while I think (check the
git log if interested).
You could switch to filters. Here's an ugly hack for removing titles
on my web-site (the title is already inserted in a shared preamble).
#+BEGIN_SRC emacs-lisp
(defun rasmus/org-html-ignore-title-if-present (string backend info)
"Strip title if it's already there. Ignore BACKEND and INFO."
(when (and (org-export-derived-backend-p backend 'html)
(string-match "h1 class=\"mytitle\"" string))
(replace-regexp-in-string "<h1 class=\"title\">.*?</h1>" "" string)))
(add-to-list 'org-export-filter-final-output-functions
'rasmus/org-html-ignore-title-if-present)
#+END_SRC
Hope it helps,
Rasmus
