How to use browser cache (Wordpress)?

Question

htaccess

I check the site on Google pagespeed, and there is one obligatory advice left: Use the browser cache. I added the following code to the htacces file

FileETag MTime Size
<ifmodule mod_expires.c>
<filesmatch "\.(jpg|gif|png|css|js)$">
ExpiresActive on
ExpiresDefault "access plus 1 year"
</filesmatch>
</ifmodule>

But Google pagespeed still shows this remark .. Tell me, maybe you need to configure it somehow differently? And caching plugins are worth WP Super Cache
Thanks in advance!

Everything is correct, but you need to see which files are not cached and add their extensions to filesmatch.
I do not remember if Pagespeed shows a list of such files, but the same GTMetrix will definitely show them.
Edit: and add mod_headers, something like this:

<ifModule mod_headers.c>
    <FilesMatch "\.(html|htm)$">
        Header set Cache-Control "max-age=43200"
    </FilesMatch>
    <FilesMatch "\.(js|css|txt)$">
        Header set Cache-Control "max-age=604800"
    </FilesMatch>
    <FilesMatch "\.(flv|swf|ico|gif|jpg|jpeg|png)$">
        Header set Cache-Control "max-age=2592000"
    </FilesMatch>
    <FilesMatch "\.(pl|php|cgi|spl|scgi|fcgi)$">
        Header unset Cache-Control
    </FilesMatch>
</IfModule>
