Now, with WordPress 4.2.2 version is everything working.
I’m having the same issue here.
I’m in a big trouble, cuz i have a big product developed by using WordPress as the base and i have an important feature of my product attached to this synchronization.
I’m in trouble with my 50+ customers … i dont know what to do!
Good miguelsaddess, it’s worked for me, i forgot to call wp_footer() for some reason. I’m using the 3.6 WordPress version.
