  • What version of WordPress are you using? I don't see `Controls_Stack` class anywhere in this file ( **wp-includes/functions.php** ). – vee Mar 25 '22 at 13:50
  • If you are using Elementor, the current version is [3.6.1](https://wordpress.org/plugins/elementor/). Your errors tell that you are using 3.1.0. So, please update both WordPress and the plugins. – vee Mar 25 '22 at 13:53

Use ob_end_clean() function instead of ob_end_flush();
