What Causes the “ERR_CACHE_MISS” Error?

This error typically appears when you try to reload a page that was reached by submitting a POST form (like a checkout page, login form, or search result). Chrome cached the original POST request data. When you reload, Chrome asks whether to resubmit the form data. ERR_CACHE_MISS appears when Chrome cannot retrieve the cached form data needed to reload the page. It also appears when a page requires fresh data that is not in the cache and the server cannot provide it.

How to Fix It — 5 Methods

1 Click "Continue" on the Confirm Form Resubmission dialog ▶

When Chrome shows "Confirm Form Resubmission" before ERR_CACHE_MISS:

  1. Click "Continue" to resubmit the form data and reload the page
  2. Be aware this may resubmit a payment or form — check before clicking
2 Navigate back and resubmit the form ▶
  1. Press the Back button in Chrome
  2. You will return to the form or previous page
  3. Resubmit the form or complete the action again
  4. This is the safest approach to avoid duplicate submissions
3 Clear Chrome cache and cookies ▶
  1. Press Ctrl+Shift+Delete
  2. Select All time → check all boxes including Cached images and cookies
  3. Clear data
  4. Navigate to the site fresh and try the action again
4 Open in Incognito and retry ▶
  1. Press Ctrl+Shift+N to open Incognito
  2. Navigate to the site fresh
  3. Complete the form or action again
5 Disable cache in Developer Tools (for developers) ▶
  1. Press F12 to open Developer Tools
  2. Go to the Network tab
  3. Check "Disable cache" at the top
  4. Keep DevTools open and reload — Chrome will fetch everything fresh from the server

Frequently Asked Questions

Is ERR_CACHE_MISS dangerous?
No. It is a browser cache issue, not a security problem. It just means Chrome needs fresh data that it cannot retrieve from cache.
Why does ERR_CACHE_MISS happen after submitting a payment?
Payment pages use POST requests. If you try to reload the confirmation page, Chrome cannot resubmit the payment data (which is correct — to prevent duplicate charges). Go back to the site and check your account for the order.
How do I prevent ERR_CACHE_MISS on my website?
After processing a POST form, redirect users to a GET page (the "Post-Redirect-Get" pattern). This way reloading the page just reloads the GET confirmation page, not the form submission.
