APO for subdomain is still not working with updated plugin version 3.8.6

[doctorkaraca]

Continuing the discussion from WP APO : Wordpress on domain and subdomain:

Hello Dear @yevgen:

I did follow the instructions and was able to enable the APO for my subdomain on my cards using the global API token for my subdomain and a newly generated token for my root domain. My subdomain appears on my APO card.

When I check my headers, I still see

1. cf-apo-via: origin,cookie
2. cf-cache-status: DYNAMIC
3. cf-edge-cache: cache,platform=wordpress

I have flushed my cookies a number of times in multiple times, using different machines and browsers but still I get the same results.

Am I missing something?

Can this be because of WooCommerce or YITH Wishlist Plugin Cookie? It the cookie is the reason, is there a way of going around it?

My subdomain in question is https://shop.doctorkaraca.com.

I confirm the issue.

Looks like APO works now.

Good to know, for a reference there is no difference how APO works on subdomain vs root. The only reason why we restricted access from the beginning was to make sure we ran APO only against WordPress sites, ideally with CF plugin installed.

And to answer my own dumb question, yes, it was the presence of WooCommerce and YITH wishlist cookies that was preventing the cached pages from showing. Once disabled, subdomain caching via APO works like a charm. Great job and thank you very much for your hard work!
