WP Fastest Cache error while updating post

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
