Unsafe JavaScript attempt to access frame with URL

I've incorporated Vimeo into a WordPress theme I'm building, and I get these errors:

Unsafe JavaScript attempt to access frame with URL http://themes.ibrogram.com/beta/blog/ from frame with URL http://player.vimeo.com/video/4749536. Domains, protocols and ports must match.


Unsafe JavaScript attempt to access frame with URL http://themes.ibrogram.com/beta/blog/ from frame with URL http://player.vimeo.com/video/28496744?title=0&byline=0&portrait=0. Domains, protocols and ports must match.

It also (I think) is the reason for the page still loading: http://themes.ibrogram.com/beta/blog/

Read something about Javascript access security here:


Specifically about implementing Vimeo and JavaScript unsafe access, I found this on a discussion on the Vimeo forums:

If you're using a webkit browser (Safari or Chrome) that error is actually coming from the Webkit Inspector trying to access the iframe (the Webkit Inspector is actually written in HTML and Javascript).

The thing to make sure is that you can't call any of the api or addEvent methods on the iframe until the player has finished loading. As per the example, you need to add the "onLoad" event first and then execute your code inside of that handler.


And second, I checked link you provided, and it loads fast and fine to me, so it is definitely not reason why you keep having this page loading long time
