MySQLi Log In not working

Win 10, DW CC 2014, installed extensions OK, have a Log In page, form with post method, input type email, input type password, button type button - changing to submit, have not been able to make it work, maybe this will make a difference. Nope, the page is submitting but not redirecting, going back to itself and can't display itself.
I have a MySQLi connection.
<?php require_once('../Connections/IFRMi.php'); ?>
<?php require_once('../webassist/mysqli/authentication.php'); ?>
<?php
if (($_SERVER["REQUEST_METHOD"] == "POST") && (isset($_SERVER["HTTP_REFERER"]) && strpos(urldecode($_SERVER["HTTP_REFERER"]), urldecode($_SERVER["SERVER_NAME"].$_SERVER["PHP_SELF"])) > 0) && isset($_POST)) {
$Authenticate = new WA_MySQLi_Auth($IFRMi);
$Authenticate->Action = "authenticate";
$Authenticate->Name = "";
$Authenticate->Table = "users";
$Authenticate->addFilter("Email", "=", "s", "".(((isset($_POST["email"]))?$_POST["email"]:"")) ."");
$Authenticate->addFilter("Password", "=", "s", "".WA_SHA1Encryption((((isset($_POST["password"]))?$_POST["password"]:""))) ."");
$Authenticate->storeResult("Email", "UserEmail");
$Authenticate->AutoReturn = false;
$SuccessRedirect = "../members/profile.php";
$FailedRedirect = "access-denied.php";
if (function_exists("rel2abs")) $SuccessRedirect = $SuccessRedirect?rel2abs($SuccessRedirect,dirname(__FILE__)):"";
if (function_exists("rel2abs")) $FailedRedirect = $FailedRedirect?rel2abs($FailedRedirect,dirname(__FILE__)):"";
$Authenticate->SuccessRedirect = $SuccessRedirect;
$Authenticate->FailRedirect = $FailedRedirect;
$Authenticate->execute();
}
?> and
<form name="login" class="w3-container" method="post">

Try using the button press trigger instead of the current page submit trigger. If you still have issues I'd need FTP access and a url to debug.

"button press trigger" does not exist, I'm attaching a screenshot of the available options.

Give your <button> a name attribute and then it should show up in the list.

I added the attribute name and id, the server behavior trigger is "Button: login pressed" but there is no change, the page displays This page isn’t working - localhost is currently unable to handle this request.- HTTP ERROR 500When I refresh it brings the log in page again.

Can I get FTP access and a username and password to test with? I'll debug it and let you know what the issue was.

Here you go

There appears to be a bug with using dollar signs ($) in passwords. I'll have to do an update to get it corrected.

This issue should be fixed. You can download and install the latest version of the extension to correct it.

I'm getting this error removing the MySQLi extension:
While executing timer in WA_uninstall2.htm, the following JavaScript error(s) occurred:
At line 168 of file: "C:\Users\Francois Daoust\AppData\Roaming\Adobe\Dreamweaver CC 2014.1\en_US\Configuration\WA_Installer\Library2\WA_XML.js": XMLString has no properties

I've "removed" the extension, downloaded the new one and installed it, no change to the log in page.
