Hi Admin
I find out if I disable System - JFBCSystem. The social content locker is no error.
But I need to use jfbcoonect in my site.

Hello Despair
Find and open file: components/com_jfbconnect/libraries/provider/facebook.php go to line 417 and changed

$script = $debugEnabled ? "sdk/debug.js" : "sdk.js";
To
$script = $debugEnabled ? "sdk/debug.js" : "all.js";
