Hello Author
I have figured out that this issue is due to admin-style.css file.
I have emptied admin-style.css file and then each and every thing works fine. else it shows a blank page.

plz cnfrm which line in css file needs to be changed.

Thank you

Hello Author

I have deleted following lines from file admin-style.css and issue is resolved.

td {height:40px;}
td.note {height:5px;}
td.cgnote {height:1px;}

Deleted lines no 11- line no 13 in admin-style.css file
i am surprised and confused with this. that why image picker was not opening as above css lines have nothing to do with Media picker box..

Hi Marco. I have the same issue on WP 4.5.1. When in Post creation/edit ‘Add Media’ button fails to open media picker – same thing with ‘Set Featured Image’.

Presumably the wonderful key 4ce plugin is including stuff in the admin pages – does it really need to do that? I posted originally a work around to deregister the CSS for Admin however I suspect this workaround is no longer working? Maybe the references have changed?

This seems to work – just add it to your theme functions.php as usual

/* key4ce ost bridge css fights with WP admin screens for mailpoet editor & post editor in 4.5- disable the CSS while viewing these admin screens */
add_action( 'admin_head', 'my_deregister_css2', 100 );

function my_deregister_css2() {
   if (false !== strpos($_SERVER['REQUEST_URI'], '/wp-admin/admin.php?page=wysija_campaigns')) {
	wp_deregister_style( 'ost-bridge-admin' );
   }

   if (false !== strpos($_SERVER['REQUEST_URI'], '/wp-admin/post.php')) {
	wp_deregister_style( 'ost-bridge-admin' );
   }
}
