Fatal error: Call to undefined function WA_Auth_RulePasses()

Hello, After applying the Security Assist "Logged in as Admin" secure page rules to my admin area for the store (as directed in eCommerce Webinar 2), my whole admin area now gives me the following error:

Fatal error: Call to undefined function WA_Auth_RulePasses() in /homepages/30/d404790350/htdocs/campargo-new/admin/index.php on line 228

I looked in the forums for similar errors, but I didn't see a fix that applied to this.
Thanks so much!

The function WA_Auth_RulePasses() should be in the file helper_php.php

make sure this file is in the correct place on the server

Thanks for the message - I found the helper file in webassist/security_assist folder. I re-uploaded it to that folder in case it wasn't uploaded for some reason and I also made a copy of the file in both the admin folder and the root folder and I am still getting the error. Can you tell me where this file is actually suppose to be?

This is the code in the files that reference the helper file in case it helps:
<?php require_once( "../webassist/security_assist/helper_php.php" ); ?>
<?php
if (!WA_Auth_RulePasses("Logged in to admin")){
WA_Auth_RestrictAccess("");
}
?>

Thank you!

the admin/index.php file did not have this line on it:
<?php require_once( "../webassist/security_assist/helper_php.php" ); ?>

I added it at line 1.

thanks so much!

you're welcome.
