you had added the access restriction code to the connection file Connections/test.php:
<?php require_once( "../webassist/security_assist/helper_php.php" ); ?>
<?php
if (!WA_Auth_RulePasses("Logged in to pcms2_users")){
WA_Auth_RestrictAccess("index.php");
}
?>
that was causing the access to the admin/index page to fail.
