Getting blank screen with APO


WordPress 5.5.3
Cloudflare Plugin 3.8.6

With APO on, I’m getting a blank screen. HTML body is empty.

For testing, I’ve switched off all Plugins, except Materialis Theme without success. Still getting a blank screen.

Only not existing pages (http404) show what expected.


could you link to the zone you have APO issues?

Hi yevgen,

Wordpress is running on

For me the site is up and running.

Thanks @M4rt1n for feedback, but because is in production, APO is currently inactive.

I confirm an issue, we will release a fix early next week as we are in the code freeze period due to US holidays session.
