Upgrade Nginx 1.19.5 > 1.25.x

I'd first update to Centmin Mod 130.00beta01 https://community.centminmod.com/threads/centmin-mod-124-00stable-130-00beta01-releases.22673/ if you want yo use Nginx 1.25 which has support for it and automatically makes any changes to the standard Centmin Mod Nginx vhost template for existing vhosts where applicable. Though for now Nginx 1.25 specific change is just a warning message that does not impact Nginx run time operation until future versions https://community.centminmod.com/threads/nginx-1-25-1-release-http2-parameter-deprecation.23890/

Most of the automated changes done will be from Nginx 1.19 to 1.24 changes. You can always downgrade Nginx Version due to issues you find from Nginx config test command

Code (Text):

nginx -t
