Warning: touch() [function.touch]: Unable to create file…

After updating to WP 4.0.1 my facebook feed started spitting out this error message both before the feed itself, and within the feed:

Warning: touch() [function.touch]: Unable to create file /home/keepsquawt/domains/keepsquawtrue.org/public_html/wp-content/plugins/feed-them-social/feeds/facebook/cache/fb-page-177305978966528-num5.cache because Permission denied in /home/keepsquawt/domains/keepsquawtrue.org/public_html/wp-content/plugins/feed-them-social/includes/feed-them-functions.php on line 1176

Here is the shortcode that I am using:
[fts facebook id=177305978966528 posts_displayed=page_only height=600px type=page]

I have tried clearing the cache, regenerating the shortcode, deleting and re-installing etc. Nothing works.
