WordPress 5.9

Hi,
Maybe this helps to narrow your search for error:
I am on Azure Linux Web apps.
Works fine for me using WP 5.9, PHP 7.4 and Apache.
Have an issue with WP 5.9, PHP 8.0 and Nginx (see topic in this fora).
Both set-ups write files to cache directory and serve files from cache.
Cache directory protection problems? (or for file advanced-cache.php in wp-content/)?

Can you enable debugging in wp-config.php and provide more details?

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', true);
error_reporting(E_ALL | E_STRICT);

Only lines involving cache-enabler, all warnings.
Note this path does exist, there is an http-index.html and https-index.html in the folder. Also this is not the page actually being accessed in my testing. Also there are no read-write issues on the directory. and the advacnced-cache php is updated correctly.

I appear to have fixed this. I had upgraded to plugin to 1.8.7 after upgrading wp to 5.9. In wp-content\settings\cache-enabler, even though the directory had write permission, the settings file for my site still had 1.8.5 for the version number. I manually updated that to 1.8.7 and caching started working.
My curiosity is piqued though. I see nothing in documentation about that file. That file doesn’t update when I update settings via wp-admin. But error would seem to indicate that file gets preference over database? Also, while I know the caching is working by site responsiveness/cpu utilization. I notice the plugin is no longer creating http(s)-index.html files, just the empty directory structure. Also neither method from FAQ to determine cache use (html src or response header) indicate to me that its working, but it obviously is.

Wordpress is a very minor side responsibility of mine, and I’m thankful for the great plugin. I thought I understood how it worked, now I’m a bit confused.
