Pwer CMS/SecurityAssist conflict ... still an issue?

//require_once( "../WA_SecurityAssist/Helper_PHP.php" );
the security assist helpers are used for the live edit functionality, this will create a conflict on pages that have security assist applied.
If you want to maintain live edit on the other pages of you site you can create a copy of the WA_CMS.php file and comment the security assist line there, but leave it intact in the the other version. then in the developer notes for the security assist pages, attach the WA_CMSCopy.php page instead of the one that has the security assist include intact.

I'm running into this same errors here. This post was from 2010, is this still an issue today? I'm a little confused about the work-around. I would like to have the Live Edit capability, but some pages need to be secured. Is there a better way (yet)?
