error “expects parameter”

Hi Tim (or anyone else!)

This error appears on the page if I do not enter an ID reference in the short-code placed on the page:

Warning: krsort() expects parameter 1 to be array, null given in /home2/stratgf7/public_html/2017/wp-content/plugins/easy-facebook-feed/includes/class.eff.php on line 87

Warning: array_slice() expects parameter 1 to be array, null given in /home2/stratgf7/public_html/2017/wp-content/plugins/easy-facebook-feed/includes/class.eff.php on line 88

Warning: implode(): Invalid arguments passed in /home2/stratgf7/public_html/2017/wp-content/plugins/easy-facebook-feed/includes/class.eff.php on line 89

with the id variable set, I do not get the error. but, I also don’t get any content. i posted a (“public”) comment to generate some results. nuffin’ there.

Seen anything like this?

I’m thinking it’s something in my theme that may be wrecking the works. But, I’m not good enough w/coding to dig into that.

Ideas welcome!
