I'm using Org mode 9.2.3 and Emacs 26.2.

When I try to execute all source blocks of an org document with org-babel-execute-buffer (bound to C-C C-v b), I always get the following error message:

Symbol's definition function is void: org-outline-overlay-data

I'm not sure I'm uderstanding. According to the release notes of Org mode 9.2, this function has been removed and replaced by org-save-outline-visibility.

Is this a bug I should report, or am I missing something?

Thanks!

EDIT: The org package has been installed through the Package Menu Buffer, using the GNU repository. I could indeed have two versions of org that are in conflict, since I can see that both org 9.1.9 ('built-in') and org 9.2.3 are displayed in the package menu buffer.

    You probably have a "mixed" installation where an old version of org-mode is interfering with the current version. How you resolve it depends on how you installed your current version. Please edit the question and describe how you installed org-mode. Commented Jul 8, 2019 at 17:16

However, I can also read in the package manu buffer that org 9.2.3 "is shadowing a built-in package". Commented Jul 8, 2019 at 22:10

Problem solved. I found this info on org website:

Using Emacs packaging system

Recent Emacs distributions include a packaging system which lets you install Elisp libraries. You can install Org with M-x package-install RET org.

Important: You need to do this in a session where no ‘.org’ file has been visited, i.e., where no Org built-in function have been loaded. Otherwise autoload Org functions will mess up the installation.

Indeed, I might have installed org when some org files had already been visited with the "old" 9.1.9 version. I just reinstalled Emacs and all the packages, and this solved the problem.

Thanks!
