Hello.

I'm new to nginx. I installed it on Fedora 31 workstation, with Wordpress. Nginx and PHP work (php.info works), but Wordpress doesn't. My 1st problem is that when I go with Firefox to mysite.com/wp-admin∕setup-config.php, a Wordpress page is displayed but stat setup-config.php says that setup-config.php has not been accessed recently, even if I had cleared Firefox cache just before. The same is true if I use curl. And I read on the net that Nginx doesn't cache by default... And curl says "Cache-Control: no-cache, must-revalidate, max-age=0". And when I go to mysite.com/wp-admin∕install.php , I get a blank page and stat says the file has not been accessed recently either...
So it seems these files are cached, but by what program? And how to clear the cache?

Thank you for any help.
