Wordpress plugin bug: cache-control not respected after uninstall

[PeterJ]

Result

Cloudflare serves a cached copy of the page that can be days old

Expected

the html page not to be stored at all ever and only a live version of the page sent

Workaround consided but rejected

Purge the cache myself but this has negitive side effects and does not
solve the issue of dynamic elements being served staticly

FireFox cache problem

I have a cache problem in FireFox. When something changes on my website, Firefox doesn’t show the changes. This problem does not occur on e.g. Chrome, EDGE. The only solution is to force FireFox to read by using CTRL + F5. Then it shows the changes on the website. When I turn on development mode on CF the problem with firefox disappears. When I open the page in a private window, the problem don’t disappears. Is it a problem with the FireFox itself, or is there something wrong with my CloudFlare …

@PeterJ

cf-apo-via: cache

Looks like you are using APO for WordPress. You may disable it and try again.

thanks for the speedy reply.
the plugin was uninstalled via wordpress looks like that did not turn off the cloudflare end.
reinstalled the plugin and turned it off for good this time. that was driving me crazy.
