Hi Derek,
First of all please accept our apologies for the delay in responding to you. We are experiencing an unprecedented demand for our Free service which is causing delays for our Free customers.
We have plans to update our plugin but for now, there’s no ETA on when this will happen. I do apologize for the inconvenience.
I will recommend that to remove the Cloudflare WordPress plugin if you wish to upgrade PHP.
There’s no need to use Cloudflare WordPress Plugin for Cloudflare features to work.
Please let me know if you have any questions regarding this ticket.
Kind regards

Just get rid of the plugin.

It’s been like 1 year and 11 months.. Oh, or keep it if you enjoy php 5.6 instead or anything remotely updated. And ignore the “how to” http2/server push to work for wordpress… which adamantly says use the plugin! as half of the answer. They have more important things to worry about than WordPress, which powers… 28%? of websites in the world. When you’re making money and only focused on IPO, that’s what happens. Have to be grateful for what it has, which is still better than otherwise definitely. But the plugin should be removed entirely.

Companies that are so big and soo worried about IPO you’d THINK would have enough employees to say to have 1 single actual answer for a CMS that powers (looked it up just now) 32% of sites across the world.

So do yourself a favor and uncross your fingers.

Many of us can’t get rid of the plugin, or even ugprade it to the latest version without it breaking our site
