No notification into facebook wall

Ensure you're running 2.5.3 of JFBConnect. Also, verify that your user plugin ordering is correct (Joomla, then JFBConnect).

I couldn't find the login button your page, so I couldn't do some testing. How is JFBConnect configured? Create New Users- Yes/No? When you try to register a new Facebook account the first time, are you asked "Do you want to give this site permission to post", or something similar?

Thank you for setting it back up.

We think we've found the problem. If you could make the one-line change below, it should fix your issue. The problem is that the correct Facebook Connect Javascript API is not being initialized on every page as it should be. Without this, we can't make the calls to FB to check if status update permissions are set (or to ask to grant them). We'll include this fix in a future release as well.

Please let us know if this works:
In the component/com_jfbconnect/views/loginregister/tmpl/default.php file, at line 11 right under the "include_once" line, add:

defined('_JEXEC') or die();
require_once (JPATH_ROOT.DS.'components'.DS.'com_jfbconnect'.DS.'helpers'.DS.'facebookhelper.php');
JFBConnectFacebookHelper::init();

Glad to hear it. We've patched this into the next release so you won't be affected.

That line needs to be added in 2.5.3. We haven't released 2.5.4 yet as few people are affected by this issue. Sorry that you're included on this list. We hope to have another release out soon.
