       Fatal error: Uncaught Error: Call to undefined function insert_with_markers() in /home/domain.com/public_html/wp-content/plugins/wp-cloudflare-page-cache/libs/cache_controller.class.php:2095 Stack trace:
       #0 /home/domain.com/public_html/wp-content/plugins/wp-cloudflare-page-cache/wp-cloudflare-super-page-cache.php(775): SWCFPC_Cache_Controller->write_htaccess('')

       #6 {main} thrown in /home/domain.com/public_html/wp-content/plugins/wp-cloudflare-page-cache/libs/cache_controller.class.php on line 2095
       ```
   
 * I temporarily fixed it by commenting the following line in cloudflare-super-page-
   cache.php(775).
    `$objects["cache_controller"]->write_htaccess( $error_msg );`
 * But need your attention to fix it. BTW, I am using Hummingbird Cache plugin on
   this site, and this seems to be the first time I saw this error at the very bottom
   of the frontend footer. seems like it loads everything, then through this error.
 * Thanks in advance.

 * Also, it is only happening on a website designed by the Oxygen Page Builder. 
   My other websites that’s running on the GeneratePress theme are good.

 * Hi [@mehranattari](https://wordpress.org/support/users/mehranattari/) ,
    I think
   it is somehow related to oxygen, ’cause insert_with_markers is a function of 
   the WordPress core and this is the first time someone report a fatal error like
   this.
 * Can you please share your oxygen with me to test it in conjuction with this plugin
   and find a solution? You find my email address on the plugin’s settings page.
 * Thank you

 * Btw on 4.4.3 I added a check if the _insert\_with\_markers_ function exists before
   to use it
