Failed to add wikinodes to ‘org-font-lock-extra-keywords

Question

I want to use org-wikinodes (http://orgmode.org/worg/org-contrib/org-wikinodes.html)

Org wikinode is activated :

(setq org-modules (quote (org-wikinodes)))

I can follow wikinodes links with C-c C-o.

However, the wikinodes links are not clickable. In addition, when I open an org file, I have the following message :

"Failed to add wikinodes to ‘org-font-lock-extra-keywords’."

I saw in the org-list that this problem was resolved before (https://lists.gnu.org/archive/html/emacs-orgmode/2015-06/msg00738.html)

Emacs version:

GNU Emacs 25.2.1 (x86_64-apple-darwin15.6.0, Carbon Version 157 AppKit 1404.47) of 2017-02-15

Org mode version 9.0.5 (9.0.5-elpaplus @ /Users/sam/.emacs.d/elpa/org-plus-contrib-20170210/)

Does anybody have the same issue?

Best,

Find the line towards the end of org-wikinodes.el that reads:

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

and and change it to this:

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

Then M-x byte-recompile-directory and path-to/org-plus-contrib/.

I honestly have no idea why this works... I just got lucky (perhaps someone else can chime in).

A couple of things to note about this:

If you ever update org-wikinodes.el your changes will be lost. Maybe there's a way to get this done in your init.el file instead?

I also notice that placing (setq org-return-follows-link t) in init.el has no effect links generated by org-wikinodes. No idea why...
