org-publish: Wrong number of arguments: plist-get

Question

I tried to configure org-publish with some html variables, but I'm getting this error let: Wrong number of arguments: plist-get, 3. I've debug-on-error enabled but doesn't show up the minibuffer.

This is my config .el file.

(require 'ox-publish)
(require 'ox-rss)


;; Initial configuration
(setq project-source "~/org/blog/"
      project-dest   "~/org/public/"
      website-url    "blog.me")


(setq blog-head
  "<link rel=\"stylesheet\" href=\"css/site.css\" type=\"text/css\">")


(setq blog-preamble
  "<div class=\"nav\"><ul>
  <li><a href=\"/\">Home</a></li>
  <li><a href=\"/blog/index.html\">Blog</a></li>

let: Wrong number of arguments: plist-get, 3

so yes is ox-rss the problem. I'm using this ox-rss.el locally

Solved by installing org-contrib via elpa.
