Hi folks,

I'm getting below error when I submit my custom form.

.cshtml

using (Html.BeginUmbracoForm("Signup", "Member", FormMethod.Post, new { id = "signup", @class = "site_general_form" }))

Controller

    [HttpPost]
    [ValidateAntiForgeryToken]
    [CaptchaValidator]
    public ActionResult Signup(RegisterModel model)
    {
      //Code block
    }

ERROR
