 * Hello
    I have updated wordpress to version 4.5. But i am having issues with this
   plugin. If this plugin is activated then Featured Image or Media Picker pop up
   does not opens. and it shows following warning in console.
 * `Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental
   effects to the end user's experience. For more help, check https://xhr.spec.whatwg.
   org/.`
 * Please confirm how can we fix this.
 * thank you

 * 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' );
          }
       }
       ```
