If you are completing an online form and the form contains a personal response that you provided directly to your browser, it is a good idea to copy it and save it to a file before submitting the form. This is because if the form fails to submit for any reason, the information you provided may be lost. Some forms store user-entered information, others do not.

Correction Confirm resubmission of the form when updating

Confirm resubmitting the form in an update error means that when you submitted the form, the data was not sent to the server to which it should be sent. This can be a problem, for example, if you are not connected to the Internet or your Internet connection is unstable and disconnected before data can be sent. This can be a problem on the website side, i.e. the server is not responding, data analysis is taking too long, the server is waiting for different data, etc.

In some cases, the user can fix the form resubmission update error, but in other cases, it can be a problem on the website and you will need to contact your webmaster. Try the fixes below as an end user to resolve the error.

1. Check your browser session

A browser session may be one reason you may see a “Confirm Form Resubmission” error message when updating. The message may appear in any browser in a slightly different language, but make sure

  • You are not using the incognito browser window
  • You will not update the form manually after you submit
  • You have not installed any applications or extensions that may interrupt the session, such as VPN, network traffic control, proxy, user agent switch, and so on.

You may want to use a different browser than the one you are using if the error persists. Use a modern browser like Chrome or Opera instead of Firefox or Safari. If you see this error in your mobile browser, switch to a desktop browser.

2. Clear your browser information and resubmit

There may be a problem confirming the resubmission of the form during the update because the server is under heavy load and too many forms are being sent at the same time as you submit it. You can try to wait until the server is overloaded, but in the meantime, clear your browser information and try sending the form again.

These fixes apply if you can change the form code. In both cases, the Confirm Resend on Upgrade form will appear if there is no problem with your server.


PHP forms can send data in two ways; POST or GET. If you are using the POST method, you will receive a Confirm Form Resubmission Error during the upgrade, but you will not see it using the GET method.

This means that there is a problem adding a POST command to the form or the user updates the form before submitting it. The POST method should only be used when necessary, for example with password reset fields, not in standard form fields.

Disable transmission verification in your browser

Browsers can use their own form controls. This is usually a feature, but you can force the page to bypass browser verification. You can do this using the AJAX form. You can still use POST with it if you do not want to go to GET.
