Don

Well, I’ve figured it out. I got the alert as described when I submitted the form from inside a JavaScript function instead of clicking the form submit button. I’m not sure what’s the difference between those but I’m happy that I finally found a solution.

To clarify: instead of form.submit() I now do submitButton.click() from inside my custom form submit function (after checking if the form is valid). The submit button is stil present in the form but it’s hidden.

Thank you @rainfallnixfig. I have updated the db version. The issue disappears once I remove the custom form-checkout.php. The issue is in my custom theme.

I’m now looking for an solution on how to prevent the alert from showing up in my custom theme before submitting the order. I can’t find what’s triggering the alert.

Thank you @daniyalahmedk. Below the system report.

Hi Karolina,

I’ve just rated the plugin 5 stars since it’s the least I could do.

The console doesn’t show an error or anything.
Above the page it even says “settings saved” after submitting the save.

If I change the name it saves the changes but it won’t save when changing the flat fee or percentage fee.

Best regards,
Don
