Hey guys, Ivan from Iframely here. Signed up on support request. @julian @baris - please tag me next time, we'll try to keep an eye on your forum.
Because the plugin works with the cloud version, the issue in this thread is obviously about integrating Iframely self-hosted version and/or connecting it in the plugin's configuration. We'll request additional info take care of it at Iframely support. Thanks for chiming in!
