Title: Clear cache Last modified: July 4, 2020 --- # Clear cache * Resolved [Patrick Thagaard](https://wordpress.org/support/users/patrickthagaard/) * (@patrickthagaard) * [5 years, 11 months ago](https://wordpress.org/support/topic/clear-cache-12/) * Hi, * We are running LS with QUIC cache. * When i clear the LS cache and flush the QUIC cache (both) it looks as if the users browser-cache is still “active” so they get an old version. (currently where AJAX is returning a 400 error). * Is there a way to SKIP cache on frontend or force a browsercache refresh? * Im thinking a temp-solution will be doing a ?no-cache GET setup or something – but i cant see if thats possible with LS + QUIC. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fclear-cache-12%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 5 replies - 1 through 5 (of 5 total) * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [5 years, 11 months ago](https://wordpress.org/support/topic/clear-cache-12/#post-13072792) * Hi, * > When i clear the LS cache and flush the QUIC cache (both) it looks as if the > users browser-cache is still “active” so they get an old version.

I mean like how did you check it ? * ajax 400 is different story. * Best regards, * Thread Starter [Patrick Thagaard](https://wordpress.org/support/users/patrickthagaard/) * (@patrickthagaard) * [5 years, 11 months ago](https://wordpress.org/support/topic/clear-cache-12/#post-13073334) * We run a membership website where logged-in cache is active, to privately cache the pages. * However; for our LMS setup we have a button that “starts” the course. When this button is pressed; the website will continue to show the cached version of the site (where the button is still telling users to start the course) * (If the user forced empty cache in chrome; then they’ll see the right page. But if they update (F5) then they’ll go back to the old cached site without having the course started) * Same goes for our login-popup where the user logs in; but it doesnt register on their front end. Clear cache in chrome and it works correctly (or log in again– then it shows correctly) * Im not sure what im missing here or how to clear the content upon login/course- start etc. and figured there was something i could hook into to fix it. * The login popup is default in flatsome. The LMS system is woocommerce’s SENSEI * (Flatsome also has no UX Builder exempt like Divi so i assume things arent compatible with it) - This reply was modified 5 years, 11 months ago by [Patrick Thagaard](https://wordpress.org/support/users/patrickthagaard/). - This reply was modified 5 years, 11 months ago by [Patrick Thagaard](https://wordpress.org/support/users/patrickthagaard/). * Plugin Support [qtwrk](https://wordpress.org/support/users/qtwrk/) * (@qtwrk) * [5 years, 11 months ago](https://wordpress.org/support/topic/clear-cache-12/#post-13074991) * Hi, * Could you please post full HTTP response header on any of these page in question? * Best regards, * Thread Starter [Patrick Thagaard](https://wordpress.org/support/users/patrickthagaard/) * (@patrickthagaard) * [5 years, 11 months ago](https://wordpress.org/support/topic/clear-cache-12/#post-13076587) * This is the header from SENSEI “Start Course”: * ``` Request URL: https://www.femaleinvest.dk/course/modul-3-tips-og-tricks/ Request Method: GET Status Code: 200 (from ServiceWorker) Referrer Policy: no-referrer-when-downgrade access-control-allow-headers: * access-control-allow-methods: * access-control-allow-origin: * cache-control: no-transform, no-cache, no-store, must-revalidate content-encoding: br content-type: text/html; charset=UTF-8 date: Mon, 06 Jul 2020 09:07:42 GMT expires: Wed, 11 Jan 1984 05:00:00 GMT link: ; rel="https://api.w.org/", ; rel=shortlink, ; rel=preload; as=style,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script,; rel=preload; as=script server: LiteSpeed status: 200 vary: Accept-Encoding,User-Agent x-litespeed-cache-control: no-cache x-litespeed-tag: 884_ x-qc-pop: EU-DK-Copenhagen-30 Provisional headers are shown.
