Hello,
I have tried Chrome on Windows 10, Microsoft Edge, and Chrome on Android, but I still have no luck getting the plugin to work. I have my API key saved and I’ve tried minimal shortcode, but I am only greeted with a black screen. My browsers are not even asking for permission to use the camera or microphone. I am running a WordPress Multisite installation, however that doesn’t change anything. I say this because I’ve also set up a separate, brand new WordPress installation that is only running the wpRTC plugin, and I still have the same problem. I have a hunch that the new release of WordPress (4.4, Clifford) might break this plugin, however I have no way of confirming this because I have only tested it on WordPress 4.4. Here is the page that it is not working on.
This looks to be a very promising plugin if it would work. I appreciate the option of a free version, and if the Pro version had a certain feature, I would be willing to pay for it.
