Wordpress APO cf-edge-cache response header is missing!

[kjsoule13]

What is the name of the domain?

Soule Media: Creative Authentic Media Production

What is the error message?

cf-edge-cache response header is missing! Please clear any server cache used via other plugins.

What is the issue you’re encountering

I don’t think the APO is working properly

What steps have you taken to resolve the issue?

I followed the instructions and went to HTTP response header check | Uptrends. I saw two of the three indicators it was working: CF-Cache-Status | HIT, cf-edge-cache | cache, platform=wordpress. But I didn’t see cf-apo-via | tcache so I added: function add_cloudflare_apo_headers() {
if (function_exists(‘header’)) {
// Add Cloudflare APO Headers
header(“cf-edge-cache: cache, platform=wordpress”);
header(“cf-apo-via: tcache”);
}
}
add_action(‘send_headers’, ‘add_cloudflare_apo_headers’);

to the functions.php file. This resolved the issue on uptrend and I now see all three indicators that its working properly: CF-Cache-Status | HIT, cf-apo-via | tcache, cf-edge-cache | cache, platform=wordpress. But I’m still getting the same error message in the Cloudflare plugin on Wordpress. Is this most likely a false error message if I can also see the proper setup when I go into my terminal and use “curl -I https://soulemedia.com” and see those three messages are working correctly as well?

It looks like it’s working now.
