Thank you for your question and I am happy to help!
Can you please share on which file types you are seeing this?
Can you please share the website URL and the .htaccess rules added by W3TC Browser Cache?
Thanks!
Thank you for the information.
Is the option still there if you disable Cache-Control header?
I can see that you are also using Cloudflare. Can you please confirm if the Cloudflare BC settings are respecting the existing headers?
Also please share your BC settings or the .htaccess rules.
Thanks!
