Why doesn't htaccess set cache timeout?

Question

Browsers

Hello. There is a site www.alexeydev.com
A site on WP and the problem is that I registered the cache storage time in htaccess

<ifModule mod_headers.c>
  <FilesMatch "\.(html|htm|php|js|jpg|png|gif|ico|jpeg|css|woff2|eot|ttf|woff|svg|otf)$">
  	Header set Cache-Control "max-age=900"
  </FilesMatch>
</IfModule>

But when I look at the headlines, there is some kind of default figure:

What could be the problem?
Thank you.

Answer 1

ifModule mod_headers.c

Maybe there is no module? And as a result, nothing works, as you asked.
B 1 more point, you have NGIX on the server, which means that htaccess may not affect anything at all. Although there are configurations where it works, in general htaccess is a file for the Apache server, not NGIX. So I think you are here
