htaccess code not working

Question

Server optimization

Good afternoon, I am speeding up the site https://learnhowblogging.com . I can't solve such problems as Gzip compression, HTTP requests, cookie-free domains, installed all possible plugins - it didn't help, I inserted a code in htaccess that usually solves these problems, but everything is fine, nothing helps, I tried to delve into the hosting settings, nothing too. What could be the problem, I would be very grateful for any help

Answer 1

And not the fact that it will work ... Because. if you have it all spinning on nginx + apache, then most likely you need to configure nginx.
Different hosting providers, different software and different setup methods...
