Dear Richard,
Thank you for your help.
I was on the 2.8 version on wordpress 4.0
What I noticed in the code (via inspect element in chrome) was the class ik_fb_facebook_link doesn’t exist in the css. (But I’m no expert, so not sure if I’m doing this the right way)
I’ve tried to put a feed in a post on the site, but it has the same problem.
The theme I’m using is Sparkling from colorlib.
Regards,
Sjoerd
