I am having trouble using org-wikinodes with the latest version of org (9.0.7). When I open my test.org <http://test.org/> file, I get a message in the mini-buffer "Failed to add wikinodes to 'org-font-lock-extra-keywords'". So after some trial and error, I changed this line in org-wikinodes:

 (let ((m (member '(org-activate-plain-links (0 'org-link t))

to this:

 (let ((m (member '(org-activate-plain-links (0 'org-link))

And now it loads — all the CamelCase words are blue, and clicking or hitting C-c C-o works as well. But... org-return-follows-link does not work.  It works fine with all other org-links. But not org-wikinode links...

Here is what I have in my init.el file:

;;; Set default directory
(setq default-directory "~/org/")

;;; Add path to src directory
(add-to-list 'load-path "~/.emacs.d/lisp")
(add-to-list 'load-path "~/.emacs.d/lisp/org-9.0.7/lisp")
(add-to-list 'load-path "~/.emacs.d/lisp/org-9.0.7/contrib/lisp" t)

;;; Load last-opened file
(desktop-save-mode 0)

;;; Stop emacs from saving redundant backup files
(setq make-backup-files nil)

(custom-set-variables
 '(org-modules (quote (org-wikinodes)))
 '(org-return-follows-link t)
 '(org-wikinodes-scope (quote directory)))

Any ideas?

Thanks!
