404 error nginx php problem.

Greetings, First of all huge thanks to all the people who wrote guides and are helping people understand more how to do stuff, now back to my question.

I’ve done everything step by step with Digitalocean’s guides; I’m running on Debian 11 dist.

Installed LEMP stack, both php7.4fpm and nginx show no errors in console they run without problem but when i’m tryin’ to install Wordpress not just when i try to see php information on my address it downloads instead of executing it. (I’ve lost about 2 plus half days researching to fix the problem but w/o progress so that’s why i created account and i’m posting this question to the community)
