<fb:request-form
action="<?=$fbconfig['baseUrl']?>/invite.php"
target="_top"
method="POST"
invite="true"
type= <?php echo $fbconfig['appname']; ?>
content="I tried this and love this, what about you ? <fb:req-choice url='<?php echo $fbconfig['appBaseUrl']; ?>' label='Accept' />"
>
<fb:multi-friend-selector
showborder="false"
actiontext=<?php echo $fbconfig['appname' ]; ?>>
</fb:request-form>
</fb:fbml>
</script>

Answer 1

Facebook has deprecated this legacy FBML plugin. While it may still work for a while, you will want to upgrade to their new Requests Dialog, which will be easier to get support for. Also, I've noticed some other deprecated features stop working lately (yet they haven't officially been killed), so this may be the case. But check the javascript console for any errors and post them.

Now to invite friends the only way is to use FB JS
the code
function showInvite()
{
<?php
if (strlen($fbconfig['appname' ])>50)
{
$title = substr($fbconfig['appname' ],0,45);
$title = $title . ' ...';
}
else
$title = $fbconfig['appname' ];
if (strlen($fbconfig['appBaseUrl'])>200)
{
$message = substr($fbconfig['appBaseUrl'],0,200);
$message = 'I just love this App, now it\'s your turn to try it # '.$message;
}
else
$message ='I just love this App, now it"s your turn to try it # '.$fbconfig['appBaseUrl'];
?>
var r = FB.ui({
method : 'apprequests',
message: '<?php echo $message; ?>',
title: '<?php echo $title; ?>',
});
}

Answer 3

Try out code on this page, it would certainly help
https://developers.facebook.com/docs/reference/dialogs/requests/
Seems like this is what you are looking for
<script>
FB.init({
appId : 'APPID',
});
FB.ui({method: 'apprequests', message: 'My Great Request'});
</script>

Answer 4

Have you tried checking the pages source/html? Maybe there are some errors reporting.
You can also in PHP call error_reporting(E_ALL); which will enable all errors to be printed instead of being hidden.
Also, perhaps you could check your browsers JavaScript logs for errors.
In Internet Explorer 9 press F12
In Firefox download firebug.
In Chrome press CTRL + SHIFT + J

function showInvite() {
<?php
if (strlen($fbconfig['appname']) > 50) {
$title = substr($fbconfig['appname'], 0, 45);
$title = $title . ' ...';
} else $title = $fbconfig['appname'];
if (strlen($fbconfig['appBaseUrl']) > 200) {
$message = substr($fbconfig['appBaseUrl'], 0, 200);
$message = 'I just love this App, now it\'s your turn to try it # ' . $message;
} else $message = 'I just love this App, now it"s your turn to try it # ' . $fbconfig['appBaseUrl']; ?>
var r = FB.ui({
method: 'apprequests',
message: '<?php echo $message; ?>',
title: '<?php echo $title; ?>',
});
}
