Hi There,

updating from Org Mode 20150713 to 20150831 (Elpa package) gives me an 
error at startup:

#+BEGIN_EXAMPLE
Warning (initialization): An error occurred while loading 
`/home/thomas/.emacs':

Invalid function: org-babel-header-args-safe-fn

To ensure normal operation, you should investigate and remove the
cause of the error in your initialization file.  Start Emacs with
the `--debug-init' option to view a complete error backtrace.
#+END_EXAMPLE

And ~emacs --debug-init~ says:

#+BEGIN_EXAMPLE
Debugger entered--Lisp error: (invalid-function 
org-babel-header-args-safe-fn)

#+END_EXAMPLE

I'm having a problem with R. In my .emacs I load R like this:

#+BEGIN_SRC emacs-lisp
(require 'ess-site) ;; see 
http://orgmode.org/worg/org-tutorials/org-R/org-R.html
(org-babel-do-load-languages 'org-babel-load-languages '((R . t)))
#+END_SRC

If I remove R from babel languages, the Error disappears.

I get the same Error when I require ob-R:

#+BEGIN_SRC emacs-lisp
(require 'ob-R) ;;  Invalid function: org-babel-header-args-safe-fn
#+END_SRC

Huh, this is odd! Am I missing something?
If not, how can I revert to 20150713?



Many thanks,
thomas

When this error has been reported in the past, it has been due to
another version of Org being loaded during the update.  Please uninstall
and then reinstall before any version of Org is loaded.
