I recently installed WP Super Cache and now something is preventing my featured image from showing in my RSS emails and is pulling in the URL of the image instead of the content in Facebook.
Example of newsletter issue: http://us6.campaign-archive2.com/?u=9570f25559c3978c46059a7cc&id=8eb0c4280e&e=330366c907
Example of Facebook post issue: https://www.facebook.com/84thand3rd/posts/553506524697346
(Note, I pull all my images in via flickr except the Featured Image which is uploaded to the media library)
Any help would be greatly appreciated. Thanks
