WPADMIN being cached

Hi,

I have the same problem.
I manage my own server with LiteSpeed server (OpenLiteSpeed).
The settings you mentioned are blank.
WP and the plugin are updated to the latest version.

I disabled the object cache and opcache and I done a Purge All, but the problem is always there.

Another thing I noticed is that every notification I have in the dashboard (for example updated plugin or cache purged), comes out when I change page and to remove it I have to refresh the page itself.

no-cache

This is the result from the home page when I logged as admin:

access-control-allow-origin: *
alt-svc: quic=":443"; ma=2592000; v="43,46", h3-Q043=":443"; ma=2592000, h3-Q046=":443"; ma=2592000, h3-Q050=":443"; ma=2592000, h3-25=":443"; ma=2592000, h3-27=":443"; ma=2592000

Now, I see the issue.

I had followed this guide: How to set up custom headers in OpenLiteSpeed but the setting of the Header Operations give me this cache issue in wp-admin dasboard.

I have removed this

unset Cache-control
set Cache-control public, max-age=15552000
set Access-Control-Allow-Origin: *

and now it is all ok.

Thank you for your support!

Oh dude, you are right! 😀
So can I set that up again? I mean this:

unset Cache-control
set Cache-control public, max-age=15552000
set Access-Control-Allow-Origin: *
