Comment:

 Actually, having read through the ticket history a bit, I think it's a
 different situation. That guy's ticket is about changing the site url from
 http to https and really doing it improperly caused the issue. We have
 been https since install. See srcset image:


 {{{
 <img class="size-full wp-image-124 alignleft"
 src="https://blogs.hope.edu/alumni/wp-
 content/uploads/sites/39/2016/02/Anne.jpg" alt="Anne" width="4511"
 height="3598" srcset="http://blogs.hope.edu/alumni/wp-
 content/uploads/sites/39/2016/02/Anne-300x239.jpg 300w,
 http://blogs.hope.edu/alumni/wp-content/uploads/sites/39/2016/02/Anne-
 768x613.jpg 768w, http://blogs.hope.edu/alumni/wp-
 content/uploads/sites/39/2016/02/Anne-1024x817.jpg 1024w,
 http://blogs.hope.edu/alumni/wp-content/uploads/sites/39/2016/02/Anne.jpg
 4511w" sizes="(max-width: 4511px) 100vw, 4511px">
 }}}

 Note that the original image src is https:// but the srcset images are all
 http://
 This is pushing the mixed content from a warning to an error, and
 therefore not showing the image at all.
