8- Err_Cache_Miss On A WordPress Site

Getting this error on a WordPress site means your browser isn’t handling the cache properly. You can try accessing that site from another browser, but if this problem keeps occurring, you can try these few steps.

  • You can try to clear the cache on your browser by going into settings and deleting all the cache.
  • The extensions on your browser can be interfering with your WordPress website, disable those extensions and try to access the website again.
  • If the above methods don’t work for you, then try disabling unnecessary plugins from your WordPress website.
  • The last thing you can try is to clear the cache from your site, you can clear the cache of every plugin by going into their settings.

Note: The cache clearing option will be different for different plugins, but usually, they are located in the settings option.

9- Disable Prompt Repost

The prompt repost option can cause Chrome to crash and show the error err_cache_miss, by disabling the prompt repost, you can avoid that. You can also avoid prompt reposting by avoiding the back and reload button on chrome.

  • Select properties from a set of options, it will open a new dialog box.
  • Find a dialog box named Target, it will be under the Target Location option.Image of properties tab of chrome
  • It will look something like this: “C:\Program Files\Google\Chrome\Application\chrome.exe”.
  • You just need to add a line after this -disable-prompt-on-repost.
  • Now it will look something like this: “C:\Program Files\Google\Chrome\Application\chrome.exe–disable-prompt-on-repost”.
  • Now click Apply and OK, and restart your Google Chrome.

Note: For this to work, you will have to need to open Chrome with this shortcut. If you opened it without this shortcut, then it will load with its default properties. I suggest you have two shortcuts for Chrome, one for default settings and the other for disabling the prompt repost.

  2. header(“Expires: Tue, 01 Jan 2000 00:00:00 GMT”);
  3. header(“Last-Modified: ” . gmdate(“D, d M Y H:i:s”) . ” GMT”);
  4. header(“Cache-Control: no-store, no-cache, must-revalidate, max-age=0”);
