Possible fix to typeError line 221

[djculex]

Hey there great plugin. However when clicking 'comments' or 'likes' in the stream I get
"TypeError: a.attachment is undefined in jquery.ibacor-fb-streaming.min.js Line 221"

In line 221 I changed

from
if (a.attachment.media.image.src != null) {

to
if (a.attachment != null || a.attachment != undefined) {

Hope this could helps someone :-)
