Chanda,
First, for the redirect to application, we've done some testing and have an update that should work for you.
(Some of this is copied from above so that other users can skip right here):
Canvas Redirection from Page Tab
You'll need to make the following edit to one of our files. Please open the /components/com_jfbconnect/libraries/canvas.php file. Around line 161, you'll see:
else
{
$tabTemplate = $this->configModel->getSetting('canvas_tab_template');
$this->setTemplate($tabTemplate);
}Change that code to:
else
{
echo '<html><head></head><body><script type="text/javascript">top.location.href = "https://apps.facebook.com/YOUR_APP_URL";</script></body></html>';
$app->close();
$tabTemplate = $this->configModel->getSetting('canvas_tab_template');
$this->setTemplate($tabTemplate);
}
As for the Comments now showing, no, I don't have any great suggestions as to why. Can you try disabling the JFBCContent plugin altogether and see if it goes away? If not, then the box isn't from JFBConnect. If it does go away, make sure your exclusion IDs are separated by a comma. Also, please try setting all display values to "None" to see if it goes away.. you can remove the exclusions at that point as well (to eliminate one more possible cause).
Finally, if the box still persists, can you link to a page with it so we can take a look?
Thanks,
Alex
