Hi - When i select post format "video" or anything else for that matter, nothing happens - The post format is set correctly, and it uses the media.php file. But the box that allows me to embed videos, doesn't come up. which in turn results in sachiko_post_format_meta() function returns NULL. I have deactivated all plugins, and I see no errors in console. I am on wordpress 4.8 What can i do? First image is how the editor looks second image is the only plugins activated.
