TwineSocial supports SSL encryption for your embedded hub. However, you may notice some errors in the console or debug window of your parent webpage alerting you to errors connecting TwineSocial.
Here’s the scoop: If the Twitter or Facebook API gives us a URL that says that the image is at http://, then we show that in the hub. We can’t simply assume https:// is available, because the source image may be on a Wordpress blog or similar that doesn’t have https. Some APIs report both an https: and http: URL, but not all providers do.
