I think I saw that, but I did not read it carefully. And since the
autocompletion (I mean <l+TAB) still gives me the #+BEGINE_LaTex it did
not occur to me that may be the problem.
By the way, I did not clone the git repo, so I should be on the master
published on ELPA.
The versions published on ELPA are from the maint branch of org git.
When I give org-version in emacs I get:
Org-mode version 8.3.4 (8.3.4-50-g83e373-elpaplus @
/home/andrea/.emacs.d/elpa/org-plus-contrib-20160509/)
On package-list-packages I have
org 20160509 installed Outline-based notes management and organizer
org-plus-contrib 20160509 installed Outline-based notes management and organizer
Correct, both are the exact same stable 8.3.x versions; just that org-plus-contrib has the packages in contrib/ folder which the other does not have.
But the mystery is still unresolved for me.. why did #+BEGIN_EXPORT syntax work for you .. May be someone else more knowledgeable can answer that.
