Browser static file caching not working

Hello! I am using WP-Optimize 3.0.13 By default in caching of headers at me it was written that caching is disabled. I set the time and pressed on. After reloading the page I have again shows what is disabled.
I looked in the file .htaccess cache settings written.
================================
# BEGIN WP-Optimize Browser Cache
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/css “access 28 days”
ExpiresByType text/html “access 28 days”
ExpiresByType image/gif “access 28 days”
ExpiresByType image/png “access 28 days”
ExpiresByType image/jpg “access 28 days”
ExpiresByType image/jpeg “access 28 days”
ExpiresByType image/webp “access 28 days”
ExpiresByType image/x-icon “access 28 days”
ExpiresByType application/pdf “access 28 days”
ExpiresByType application/javascript “access 28 days”
ExpiresByType text/x-javascript “access 28 days”
ExpiresByType application/x-shockwave-flash “access 28 days”
ExpiresDefault “access 28 days”
</IfModule>

<IfModule mod_headers.c>
<filesMatch “\.(ico|jpe?g|png|gif|webp|swf)$”>
Header set Cache-Control “public”
</filesMatch>
<filesMatch “\.(css)$”>
Header set Cache-Control “public”
</filesMatch>
<filesMatch “\.(js)$”>
Header set Cache-Control “private”
</filesMatch>
<filesMatch “\.(x?html?|php)$”>
Header set Cache-Control “private, must-revalidate”
</filesMatch>
</IfModule>

#Disable ETag
FileETag None
# END WP-Optimize Browser Cache
==================================
But for some reason it does not work. And when scanning gtmetrix also shows that you need to enable caching of static headers.
What could be the reason? Thanks!
