It appears the PlayerIO sitebox Template is broken:
https://apps.facebook.com/seedlings/
1) If you visit this I get the following pop-up error (chrome):
In order to use the { % swf ... %} tag the SWFObject.js file must be included in the page
2) The 'Invite Friends' feature seems to be also missing/broken
the last time I've seen it, if you clicked it, the page just didn't load, it just displayed 'Please wait...' but the invite box didn't appear. Now the entire 'Invite Friends' tab seems to be missing.
Can you please fix these 2 issues asap ? Thanks
