The confirm form resubmissionERR_CACHE_MISS notification shows up in your browser when you hit Refresh or try to go back.

Contrary to what many users might think, the confirm form resubmission message is not an error or a bug.

The browser is actually looking for your permission to load your submitted data while refreshing the page or going back.

You can avoid the ERR_CACHE_MISS problem simply by never refreshing a web page on which you sent some form of information or never clicking Back.

However, it’s almost impossible to never want to see the previous page you were viewing or needing to refresh your current page.

Therefore, this post will explore how to avoid the confirmation form resubmission from Google Chrome and other browsers with this issue.

8 ways to fix the Confirm form resubmission error

1. Change your browser to Opera

Why would you want to start fixing Chrome when you can easily switch to Opera, a browser less prone to errors?

Not to mention that this browser also protects you from unwanted ads with a built-in ad blocker. This feature, together with the tracking scripts blocker make Opera really fast.

And if you’re looking for extra protection, there’s nothing better than the built-in VPN service with no limitations regarding bandwidth.

Overall, Opera offers better Windows 10 integration by offering lots of out-of-the-box features like a native screenshot tool, a pop-out video player, and much more.

And if you’re looking for Instagram, WhatsApp or Facebook Messanger, their shortcuts are conveniently placed on the sidebar.



Get around errors and other inconveniences by switching to Opera, a safer, faster and more reliable browser.

2. How to turn off confirm form resubmission on Chrome

  1. Close Google Chrome browser if it’s open.
  2. Right-click on the Chrome icon and select Properties from the contextual menu.
  3. Next, go to the Target field and after chrome.exe, append the following: -disable-prompt-on-repost
  4. This makes the complete target transform to: C:\Program Files (x86)\Google\Chrome\Application\chrome.exe -disable-prompt-on-repost
  5. Click on Apply to save your changes and then hit OK to close the Properties dialog.
  6. Launch Google Chrome by double-clicking on the shortcut.

3. How to disable confirm form resubmission by deleting no-store


  1. Open the page with the form.
  2. Find the following code on the header: header(‘Cache-Control: no-store, no-cache, must-revalidate, max-age=’);
  3. From that code, delete the no-store part from the header.
  4. Next, refresh the website page with the confirmation form resubmission error.

Note: You can only fix the confirm form resubmission on the refresh/back button with this method if you can edit the page.

4. Clear your browser’s data


  1. Launch the Firefox browser.
  2. Click on the three horizontal lines icon on the top right-hand corner of the screen.
  3. Select Options from the contextual menu to open Firefox settings.
  4. Navigate to the Privacy & Security tab on the left-hand pane.
  5. Scroll down to the Cookies & Site Data section. Hit Clear Data to reveal the dialog box in the screenshot below.
  6. Check Cookies and Site Data and Cached Web Content and finally click Clear.
  7. Scroll down a little more to the History section and click on Clear History.
  8. Select a time range and check the preferred options.
  9. Hit the Clear Now button.



  1. Open the Chrome browser.
  2. Click on the vertical ellipse icon at the top right-hand corner of the screen, go to More tools > Clear browsing data.
  3. Select the relevant timeframe for which you wish to clear your data (If you wish to get rid of all your browsing data, choose All time).
  4. Mark the checkboxes for Cached images and files and Cookies and other site data.
  5. Click on Clear data.

5. Replace the POST method

The information you entered on the web page is posted using either the POST or GET methods.

While the POST method doesn’t append your entry to the URL, the server wouldn’t have access to your data.

On the other hand, the GET method appends your entry to the URL. Hence, your data isn’t as secure as the POST method.

If you can modify the page data, you can fix the confirm form resubmission issue by changing the POST method to the GET method.

To do this, simply remove the POST from the page URL and replace it with the GET method. For example, if the original code is:

<form action="index.php?load=SUBMIT"method="post">

you can replace the post part to get, so it becomes:

<form action="index.php?load=SUBMIT"method="get">

6. Make use of Ajax submit button

Use the following snippet for the submit button to disable confirm form resubmission:

type: “POST,”
URL: “bin/validation.php”
data: dataString,
success: function(){
//Insert your submission action
return false;

7. Disable corrupt browser extensions

  1. For Chrome and Firefox click the More Options icon.
  2. Find and deactivate any corrupt extensions that may be causing the confirm form resubmission Chrome issue.
  3. Refresh the problematic page.

Note: If the confirm form resubmission disappears, you know that the extension was the culprit. Leave it disabled or delete it.

  2. Select the Settings link from the contextual menu.
  3. Click Advanced from the bottom of the Settings page.
