BuddyPress.org

Hi all,

I’m trying to use Varnish cache and Varnish HTTPpurge plugin along with a Buddypress and BBpress global forum installation. Everything works fine except forum pages that are not updated correctly.

Unfortunately varnish is installed by default on my domain from my ISP so I have little or no control on its configuration. From Cpanel I have only the option to enable/disable, purge and set TTL for static and dynamic objects.
My ISP replied to me that Varnish does not work with BBPress/BuddyPress so I have to disable it. Is it true?

Using the plugin check status tool, for all my URL I get:

Varnish is running but cannot cache.
Your sever IP setup looks good. If you are using a proxy (like Sucuri or Cloudflare or Fastly) please double check that configuration and make sure to add a custom Varnish IP if necessary.
Your site is compressing content and making the internet faster.
Something is setting the header Cache-Control to “no-cache” which means visitors will never get cached pages.
Something is setting the header Cache-Control to “max-age=0” which means a page can be no older than 0 seconds before it needs to regenerate the cache.

Thank you in advance
