Wordpress Error test cache on Super Page Cache for Cloudflare Plugin

Dear Support
i used Super Page Cache for Cloudflare Plugin. It show error when i press test cache
i have an error like this picture. How to fix it?
Thanks


Page caching seems not working for both dynamic and static pages.

---

Error on dynamic page (https://webaddress): Cache status: DYNAMIC - The resource was not cached by default and your current Cloudflare caching configuration doesn't instruct Cloudflare to cache the resource. Instead, the resource was requested from the origin web server.

Error on static resource (https://webaddress/wp-content/plugins/wp-cloudflare-page-cache/assets/testcache.html): Unable to find the Cache-Control response header.

Please check if the page caching is working by yourself by surfing the website in incognito mode 'cause sometimes Cloudflare bypass the cache for cURL requests. Reload a page two or three times. If you see the response header cf-cache-status: HIT, the page caching is working well.
