Can't activate Wordpress APO

I’m getting a Bad Request error message when trying to activate APO from Wordpress on a subdomain (

Other Cloudflare settings can be sent to server so it shouldn’t be an API key issue (maybe more permissions are needed for APO ?)

I’m on latest Cloudflare wordpress plugin version

I’m seeing the APO headers from the plugin, so APO is not activating, I suggest you open a support ticket and post the ticket number here.

To contact Cloudflare Customer Support, login & go to and select get more help. If you receive an automatic response that does not help you, please reply and indicate you need more help.

EDIT: Oops, I’m seeing a no-cache header:

Thanks for your help !

I’m not sure what you mean by “APO headers from the plugin”. From Cloudflare side you mean ?

Not sure what you mean either with the no-cache header screenshot

cf-edge-cache comes from the Cloudflare Plugin, and that’s usually what APO looks for to activate.
Cache-control will tell Cloudflare to not cache that page. I don’t know if APO will override that header.

You still need to contact Support to activate APO, though.
