Could be useful for noting what postMessage does in Youtube Embed versus SoundCloud embed.. I get this message in console: Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.youtube.com') does not match the recipient window's origin ('https://mydomain.com'). @gkatsev I took a deeper look into this, it seems like it might be a timing issue with the YouTube IFrame API. The IFrame API already loads everything over https, so implementing #68 again would offer no benefits, and actually loses us the benefit of having the IFrame API do all of the lifting for creating the iframe. I have read that a combo of http and https could be the reason, but in this case both the iframe and the hosted domain is using https.. Any idea of what it can be?


Hello, This is a great theme, however the most recent update(s?) SoundCloud does note this in their Widget API#getters:; Since communication between the parent page and the widget's iframe is implemented through window.postMessage, it's not possible to return the value synchronously. Hello, First all of, looks great and very useful but just a few things: Getting the following issue currently in the console popup, I assume this is just related to localhost environment. "Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('') does not match the recipient window's origin ('')." But there are some errors like this in chrome console.

Failed to execute 'postMessage' on 'DOMWindow': The target origin provided ('https://www.youtube.com') does not match the recipient window's origin" Which versions of sdkjs-plugins, and which browser / OS are affected by this issue? Observation # 3.
