The read action changed by Facebook in early June to not have to be created in their interface ahead of time. You simply create the action type in your site of news.reads (I did this for you in your Joomla admin area already) and an object type of article (I did this as well). Then, JFBConnect can use that action.
The documentation is out of date as we prepare for the next big release, coming out by the end of this month. The documentation is correct for new actions "cooked a recipe" as you've apparently done. The 'built-in' actions, like news.reads (reading an article) don't need to be created in Facebook beforehand, like they used to.
In other words, with how I setup JFBConnect on your site, you should be ready to test the "reads an article" action right now. I'll test as a FB admin later today as well if I don't hear from you, just to make sure you get going.
Eduardo,
I'm sorry for the issues you're having. The Open Graph documentation is the only area that we think is out of date right now. That will be fixed by the end of the month with many more instruction videos and updated docs. However, the new documentation we're working on is for the updated release.
I know I'm already helping you in
this post
and
this post
. If there's something I haven't already answered there please let me know and we'll gladly help to get you going. As stated in both of those posts, the main issue it looks like you're having in both of those posts is that you're trying to use the new {JFBCAction} tag, which won't be available until the v5.1 release.
Thanks for your patience, and I do apologize for the out of date actions docs,
Alex
