Cloudflare Plugin Settings Interface Stuck in Load Loop

CF plugin installed. Domain is currently being proxied by CF.

APO was purchased from within the WP plugin. After APO was successfully purchased the plugin settings have been stuck in a load loop. When we click the CF plugin settings all that displays is the CF logo, a Home icon, Settings icon, Analytics icon and a perpetually spinning wheel between the 3 icons and the text saying Version: 4.10.1

Plugin was connected 1st with the Global API key, then to troubleshoot the plugin was disabled, a new API token was generated using CF’s preconfigured WordPress token settings. Plugin was re-activated and connected with the new token. No error is generated with either method of connecting. Settings still stuck in a load loop.

No other caching plugins are running on the WP instance. The site is the only thing on the VPS which runs Nginx and Apache.

Inspecting the site shows the cf-edge-cache header is giving the correct value but the cf-apo-via header is missing entierely as is the cf-cache-status header.
These are the response headers we’re getting:

cf-edge-cache
	cache,platform=wordpress
content-encoding
	gzip
content-length
	27514
content-type
	text/html; charset=UTF-8
date

	<https://redacteddomain.com/wp-json/>; rel="https://api.w.org/", <https://redacteddomain.com/wp-json/wp/v2/pages/69>; rel="alternate"; type="application/json", <https://quilityb2b.com/?p=69>; rel=shortlink

	Accept-Encoding

So in summary, purchasing APO trapped the plugin’s settings in a load loop and the pages aren’t being cached or delivering all the headers they should with the CF plugin running and the APO upgrade active.
