Wrong PHP version in Site Health

Site health is telling you what WordPress sees. Most servers can support multiple versions of PHP. Check both the .htaccess file for your site and an php.ini files to see if they’re picking a version other than the one you just installed.

Thanks Steve, my .htaccess file is blank and I have also changed my php.ini. Still doesn’t work …

You can’t have a working WP site and a blank .htaccess file! Anyhow, there’s something in your configuration that’s overriding the change you made to PHP and that occurs outside of WordPress. Tell me about your hosting.

I am hosting my site on Hetzner.
When I look in FTP then I see a .htaccess file with 0kb and it’s empty. It is located in this directory: /home/hikeventures/hikeventures

I also have nginx and there I have changed the line below with the PHP version installed:
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

directory: /etc/nginx/sites-available

In the php.ini which is located here /etc/php/7.4/fpm I have changed different max values.

What do you see if you try

ps -ef |grep php ?

What version of php is running?

So you have two php-fpm processes running. What happens if you stop the one from 7.2?

sudo kill -9 1131

This is clearly not a WP problem but a Linux admin issue.

Now I get an error Error 502 when I visit my site …

OK, so something in your nginx or httpd config is referencing PHP 7.2. You’re going to have to dig through your configs in /etc (and other places) as well as in the site’s root to find out what’s doing it.

Restart that php-fpm process to get your site working again.

Thanks, Steve, is there maybe a program which could trace from where this PHP 7.2 referencing comes? There are quite a lot of files …

Linux sysadmin is not for the faint of heart! I’d ask in a support forum for your particular Linux flavor.
