Thanks for a prompt reply...
Yeah it was all fine till recent spate of updates from Facebook Social Plugin, which is leaving a bad taste. I also use similar code at various places on my site. Take for example the following piece of code:
if ( isset($facebook) )
//$url = get_permalink($post->ID);
$myuser_profile = $facebook->api('/?ids='.$newurl,'GET');
// echo "Shares: " . $myuser_profile[$newurl]['shares']."\n";
//echo "Comments: " . $myuser_profile[$newurl]['comments']."\n";
echo "no facebook";
This works well at a normal php page like here, which does not has facebook plugin installed.
But does not works here (see on righthand side-bar bottom), where you see "no facebook" text. Further if i try to declare global $facebook as per php sdk by using configuration values again, it results in failure of all facebook plugin components on site like the comments box, subscribe button, like button etc..
Thus m not able to make any api calls via php sdk...
