WordPress version 4.4 is shipped with quite a few improvements. However, you may want to disable some of the new features.

How to moving the Comment text Field to bottom?

Simply add this code snippet in your theme’s functions.php file

function wpb_move_comment_field_to_bottom( $fields ) {
$comment_field = $fields['comment'];
unset( $fields['comment'] );
$fields['comment'] = $comment_field;
return $fields;

add_filter( 'comment_form_fields', 'wpb_move_comment_field_to_bottom' );

That’s all, you can now visit a post on your website as a logged out user and see the change in action.

How to disable Post oEmbed?

WordPress 4.4 introduced a post oEmbed feature which allows others to embed your WordPress posts into their own site by adding the post URL. OEmbed provides an easy way to embed content from one site to another.

If you need to disable it, first thing you need to do is install and activate the Disable Embeds plugin. It works out of the box, and there are no settings. Simply activating the plugin will disable oEmbed.

How do I disable responsive images?

WordPress 4.4 adds srcset and sizes support to WordPress. This allows the software to automatically use and display the right image based on a device’s screen size. This decreases the amount of bandwidth used to load websites since smaller images have smaller file sizes. To learn more about this.

If you need to globaly disable it, then insert into functions.php:

remove_filter( 'the_content', 'wp_make_content_images_responsive' );

Also you can disable setting the srcset attribute altogether so that all images only have a src attribute

function disable_srcset( $sources ) {
return false;
add_filter( 'wp_calculate_image_srcset', 'disable_srcset' );

That’s all.
