The form submits and nothing happens

The build was green and the interface is doing exactly what it was told.

We have not measured this one. It is invisible from the outside, and we do not open other people's forms without being asked.

What is actually happening

A form in a browser app usually calls something and then updates the interface. If the call fails and nothing checks the result, the interface still updates — because updating was not conditional on success.

That is why nothing appears in the server log either: for a great many of these the request never reached your server at all.

Where it went instead is the actual question, and there are only a few candidates: it was refused by the browser for security reasons, refused by the service on the other end, or sent to an address that does not exist in production.

Fixing it yourself

• Open the network tab, submit the form, and watch what happens. One request, and its status, answers most of this.
• If there is no request at all, the failure is before the send. If there is a request with a red status, the answer is on the other end.

Where it stops being a small job

When the request succeeds and the effect still does not happen — an email accepted by the provider and never delivered, a payment recorded as pending forever. Then the chain has more links than the browser can show you.
