ERR_CACHE_MISS: Why It Happens and How to Fix It
You fill out a form, click submit, hit the back button, and Chrome stops you with Confirm Form Resubmission and ERR_CACHE_MISS. Or a page just refuses to load and blames a cache miss. Annoying, but rarely serious.
A cache miss means Chrome went looking for a saved copy of the page and didn’t find one it could use. Usually that’s because the page was created by submitting a form, and Chrome won’t quietly resend your form data without asking. That’s a safety feature, not a bug. Nobody wants to pay for something twice because they pressed Back.
When you’ll see it
- After submitting a form, then pressing Back or Refresh.
- On checkout and login pages that don’t allow caching.
- When your browser cache is corrupted.
- When an extension interferes with how pages load.
- On websites with misconfigured caching rules.
Fix 1: Just reload the page
If you see Confirm Form Resubmission, decide whether you actually want to send the form again. For a search or a filter, go ahead and click Continue. For a payment or an order, don’t. Check your email or account first to see if the first submission went through.
If there’s no form involved, press F5 or the reload button once or twice. Temporary hiccups often clear on their own.
Fix 2: Navigate instead of going back
Rather than using Back, click a link or type the page’s address. That loads a fresh copy and skips the cache problem entirely.
Fix 3: Clear your browser cache
Press Ctrl+Shift+Delete (Cmd+Shift+Delete on a Mac), choose a time range of All time, tick Cached images and files, and click Delete data. You can leave cookies alone if you don’t want to be signed out everywhere.
Fix 4: Disable extensions
Go to chrome://extensions, turn everything off, and test the page. If the error disappears, turn extensions back on one at a time to find the culprit. Ad blockers and privacy extensions are the usual suspects.
Fix 5: Update or reset Chrome
Go to Settings > About Chrome to install updates. If the problem keeps happening on many sites, reset Chrome under Settings > Reset settings > Restore settings to their original defaults. It turns off extensions and clears temporary data, but keeps bookmarks and saved passwords.
Fix 6: Reset your network settings
ERR_CACHE_MISS sometimes shows up alongside connection problems. Flushing DNS and resetting the network stack can help. Our DNS_PROBE_FINISHED_NXDOMAIN guide has the exact steps for Windows and Mac.
Why Chrome is so cautious about forms
Think about what a form actually does. It might place an order, send a message, transfer money or post a comment. Sending the same data twice could mean two charges, two messages or a duplicate post. So when a page was built from form data, Chrome won’t store it and replay it silently. When you press Back, it asks first.
Other browsers handle this the same way, just with different wording. Firefox calls it Document Expired. Safari asks whether you want to send the form again. Different message, same idea.
Fix 7: Try another browser or profile
If one Chrome profile keeps throwing ERR_CACHE_MISS and nothing else does, create a fresh profile from the profile icon in the top-right corner, or test the site in Edge or Firefox. A clean profile tells you quickly whether the problem lives in your settings or somewhere else.
For website owners and developers
If visitors keep hitting ERR_CACHE_MISS on your site, look at how your forms and caching work.
- Use the Post/Redirect/Get pattern: after a form posts, redirect to a normal page. Then Back and Refresh don’t try to resend the form.
- Check your Cache-Control headers. A no-store header on pages people often return to will trigger more cache misses.
- If you’re testing in Chrome DevTools, make sure Disable cache isn’t left switched on by accident.
- Clear your CDN and caching plugin after big changes.
ERR_CACHE_MISS vs other Chrome errors
| Error | What it usually means |
|---|---|
| ERR_CACHE_MISS | No usable saved copy, often after a form submission |
| DNS_PROBE_FINISHED_NXDOMAIN | The site’s address couldn’t be found |
| ERR_SSL_PROTOCOL_ERROR | The secure connection failed |
Our take
If a form is involved, the error is doing its job. Just think before you click Continue. If it’s happening on random pages, clear your cache and switch off extensions. That fixes it for nearly everyone.
FAQ
What does ERR_CACHE_MISS mean?
Chrome couldn’t find a usable saved copy of the page, often because the page came from a submitted form.
Is ERR_CACHE_MISS dangerous?
No. It’s a safety check that stops your browser from resending form data without asking.
Should I click Continue on Confirm Form Resubmission?
Only if resending the form is harmless, like a search. Avoid it on payments or orders.
Will clearing my cache delete my passwords?
No. Clearing cached images and files doesn’t touch saved passwords.
Why do I get ERR_CACHE_MISS on every site?
A corrupted cache, a misbehaving extension or a network problem. Clear the cache, disable extensions, and flush DNS.
