 * Hello everyone,
 * I need your help to solve a problem I encountered when I tried to update a post
   on my WordPress site. After editing the post text, I clicked on “update” and 
   the following errors appeared:
 * Warning: Undefined property: stdClass::$zone_id in /home/caterin5/public_html/
   wp-content/plugins/wp-fastest-cache/inc/edn.php on line 227
 * Warning: Cannot modify header information – headers already sent by (output started
   at /home/caterin5/public_html/wp-content/plugins/wp-fastest-cache/inc/cdn.php:
   227) in /home/caterin5/public_html/wp-admin/post.php on line 231

 * I don’t understand the reason for these errors and how to fix them. I noticed
   that the post was updated anyway, but I’m worried that these errors could cause
   problems on my site in the future.
 * Here’s some more info:
    - WordPress version: 6.1.1
    - WP Fastest Cache version: the latest available, the plugin is up to date.
 * Can someone help me solve this problem, please? I couldn’t find any other threads
   on this matter!
 * Thank you in advance.
 * Best regards, Caterina

 * as far as I see that you have already stop using Cloudflare so you need to remove
   the cloudflare integration via “CDN” panel.

 * Hello, it’s still me! I have a huge doubt: I assumed that the CDN panel was a
   panel inside the website Cloudflare but I’m not even subscribed to Cloudflare,
   so is there another way to do what you kindly suggested? Or I misunderstood and
   I do not need to enter Cloudflare to do so?
 * Thank you once again

 * no, just you need to remove the cloudflare integration via the wp fastest cache
   panel.
