Twitter pics not showing

I've noticed lately that my Twitter pics aren't sharing and I think maybe it's because the <scopengraphplaceholder> and <sourcecoastproviderjsplaceholder> and <sourcecoastcssplaceholder> tags aren't populating once the page loads. (At least, I think maybe that's the issue?)  I do see those tags atop the page after it loads, but they're empty, and I think that's why the shares (via AddThis) aren't picking up on the photos (because the OG tags aren't there, for example).  For the life of me, I can't see to get any progress, though... we also use JCH Optimize, which is a recent addition. I added "sourcecoast" and "jfbconnect" to the exclude list. But, it hasn't worked (plus I triedJCH's debug mode & didn't see any Sourcecoast JS in their combined JS file).  It's tough to diagnose, though, as we have caching, JCH, and CloudFlare as well. So... a total pain in the rear end to figure this out. That said, I turned off caching, JCH, and CF, and this all still happened.  Any ideas or direction on how to get those tags to populate (or amybe other thoughts on how to get the Twitter pics back?).
