WordPress 4.4 Broke Media Insert?

Works fine for me. Could you please go look in your wp-content/uploads directory via FTP to see if there are any files there?

If I go to the Advanced Media Library, all the photos show up fine. It only fails when in a new blog entry, I press the “media selector” button.

I have used that button for years with no problem, until WP 4.4. I tried reinstalling the core 4.4, but no change in behavior.

FWIW, here is a link to my main blog / website which has been working for a couple yeara. Broken now. Traveling in Colombia and noway to add new blog entries since this 4.4 upgrade… ??
