 * Hi, I noticed a problem when I checked the HTTP Header. I tested it on HTTP Header
   check website and it looks like;
 * **Cache-Control:**
    max-age=3600, must-revalidate max-age=604800
 * What might be causing this problem? My WP Super Cache plugin seems working (No
   Preload, No CDN).
    In .htaccess; I have common leverage browser caching code 
   without ‘Header set Cache-Control’ though.
 * Installed plugins;
    – Akismet Anti-Spam – Really Simple SSL and Pro – ShortPixel
   Image Optimizer – Sucuri Security – Auditing, Malware Scanner and Hardening –
   tagDiv Composer – UpdraftPlus – Backup/Restore – WP-Optimize – Yoast SEO – and
   WP Super Cache obviously.
 * Please, feel free to check yourself.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fduplicate-max-age-http-header%2F%3Foutput_format%3Dmd&locale=en_US)

 * I think it’s because of Leverage Browser Caching. Wp Super Cache add “max-age
   =3600, must-revalidate” to headers. Then my Leverage Browser Caching code in .
   htaccess add max-age to headers. Currently second one shows **ExpiresByType text/
   html “access 1 hour”.** When I delete it then it shows **ExpiresDefault “access
   2 days”** (I guess). So what should I do about it? Normally, WP Super Cache and
   Leverage Browser Caching using both of them should be okay, right? Maybe delete“
   IFModule” from Leverage Browser Caching code or just live with that? Or is there
   any solution? I’m not expert guy and I’m quite lost.
