Elsewhere, you'd mentioned you tried installing both the git and ELPA versions of Org.
So that's most likely the problem. You might want to clean up and reinstall Org:
Cleanup
1. Remove the git version of org
You can use make clean-install
to remove an org installation from git. If you customized your install location, make sure to use the same settings.
2. Remove the ELPA version of Org.
In list-packages
, move point over the Org package, press d
to mark it for deletion, then press x
to execute the deletion.
Reinstall Org
Pick your favorite way of installing Org, and do that. Either the git version or ELPA version is fine, but the git version is more bleeding-edge. You shouldn't need incredibly new Org for most things, but it will have slightly more features and bugfixes.
