I've been using JW player with my portfolio since May 2011.
I have tested my JW player with every browser to date, and JW player was working fine until the most recent updates occurred.
Now, when ever I try to play ANY audio (M4A) from my portfolio to Chrome, FF, IE, or iOS browser, the jw player player does not box does not even appear on my site. Logged in or logged out. No error.
I'm upset as I've played my whole portfolio around the ability to be able to play M4A from it for potential clients.
