Thx, Senff! Work recipe for me:
Quick tip to fix it is to add this code in your functions.php theme file:
// Deregister editor-expand as it breaks CKEditor integration
function custom_deregister_editor_expand() {
wp_deregister_script('editor-expand');
}
add_action( 'admin_init', 'custom_deregister_editor_expand' );
Plugin “CKEditor for WordPress” don’t work after update to WP 4.0!
Than open post for edit with enabled this plugin, debug console of Firefox has some error messages.
Visual mode:
TypeError: c.parent(…).offset(…) is undefined load-scripts.php:76
TypeError: i.getBody is not a function input.min.js:2
HTML mode:
TypeError: c.parent(…).offset(…) is undefined load-scripts.php:76
TypeError: k.get is not a function load-scripts.php:1071
Last error message increase than i try go to visual mode.
After admin-ajax.php process get new error message:
TypeError: e is undefined load-scripts.php:318
