I need Assistance to Fix Blank Cloudflare Plugin Settings Page installed on a WP website self-hosted on Google Cloud Platform

I do not know how to resolve this issue as my WordPress website is running on a self-managed Google Cloud Platform. Could this problem be a result of file path permission?

Please can anyone assist me in resolving this challenge?

All the fixes I’ve seen did not work for me.

Something is not right at your origin server.

  1. Are there any issues reported in your WordPress Site Health?

  2. Does any other plugin have this issue? (I’ll recommend you temporarily install a new plugin to test this).

  1. Are there any issues reported in your WordPress Site Health?

No issues relating to this. The issues on my Site Health are the absence of a page cache and the recommendation to use a persistent object cache. The error relating to this issue is attached above. Err_aborted 500 (internal server error).

  1. Does any other plugin have this issue? (I’ll recommend you temporarily install a new plugin to test this).

No other plugin I tested had this issue. I tested 3 plugins, a new theme plugin, Updraftplus, and Sweep. All of these plugins run smoothly, even Sweep which is not yet tested with my version of WordPress. I also disabled Wordfence, and all my Cloudflare WAF rules, none of these helped.

I believe the issue is from my server (Google Cloud), not allowing the Cloudflare plugin to fetch data. Err_aborted 500 (internal server error).

The challenge is how to fix this now.
