I have a problem like this:

every save changes code




which is terrible beacause I have big tables and it makes final code much bigger and changes the height of empty lines.

I tried to change tinymce-advanced.php file by removing code


but it does not help.

How can I disable this?


Technically, this is an issue with TinyMCE, not with WordPress, but WP does provide a gateway to TinyMCE, which allows you to change settings. Your solution might look something like this:

add_filter ('tiny_mce_before_init', 'wpse303889_tiny_filter');
function wpse303889_tiny_filter ($in) {
  $in['entity_encoding'] = 'raw';
  return $in;

Setting the entity_encoding filter to 'raw' supposedly allows you to get rid of spaces being converted to &nbsp, but I have not tested this.

  • Hello. I added this code to class-wp-editor.php and nothing has changed. – VanWiel May 18 '18 at 18:53
  • Never change core wp files. You risk breaking stuff and changes will be lost with the first update. This belongs in your theme's functions.php file or in a plugin. – cjbj May 18 '18 at 19:11
