"ERROR" A member with this email address already exists. Try a different email

I’m having trouble with
A custom Sign up form

Working in
Wix Studio Editor.

Site link

What I’m trying to do
If you fill in the form and try and submit it, you will receive the error “A member with this email address already exists. Try a different email.” any email I try will result in this error. none of the emails I use are in the customer backend.

What I’ve tried so far
Ive checked the backend for the emails I’ve used.

Ive checked my setting.

Ive delete the field and created a new one.

Try this:

Test the published site in an incognito/private browser using a completely new email address.

After receiving the error, check Dashboard → Site Members, not only Customers or Contacts.

If the new member appears there, the first submission succeeded and something is triggering registration a second time.

Does the default form work ?

Hey There

Thanks for replying to the question.

Ive rebuilt the form, Ive tried multiple emails in incognito/private browser in google Chrome and Safari, all with the same error “A member with this email address already exists. Try a different email.”

So the default form works. So the issue is when I add custom new fields to the form.

I’m trying to capture more information in the sign up form.

Now that the default sign up form worked, I’m getting weird issues occurring in the backend. In the inbox it’s registered the input “BUT” from an old submission with all the custom fields I’d originally built into the form. It submitted the information twice.

With the default form I just submitted, it set the user as a Site Member, which in the backend, I am only allowed to set Site Members.

In the Contacts information, the labels have Custom Signup Form, Custom Signup Form 2 and Custom Signup Form 3.

Lots of weird things happening.

UPDATE

I deleted the contact and resubmitted it.

I checked the contact information which was submitted, and it had stored information from my original custom form, with the additional fields I created.

How is it doing this when now those fields have been removed from the form?

UPDATE

So I have been, adding one field at a time to the sign up form and finally received an error, which is now different to the previous one.

The field that I added to the form is a custom field I created in Contacts / … / Manage Custom Fields / This is where you create your own field.

“Couldn’t submit form due to a temporary issue. Try again later.”

So it seems like the Custom Field is the issue.

If this is the case, how do I add 2 custom field and collect the information. I tried adding the Basic Fields to the form, But it does not collect that information.

UPDATE

So I added both Custom fields that I created in the Dashboard.

Filled in the information in the field on my one machine (Safari) and still received the same error message. “Couldn’t submit form due to a temporary issue. Try again later.”

So I tried it on another machine (Google Chrome) and it works just fine. Previously it did not work on this second machine.

Now I tried it on my first machine (Google Chrome) and now it works.

Not sure what is happening here, I have not changed anything.
