I run NOF9 and use the password protection page component. NOF9 generates PHP scripts and pages for password protected webpages. I host with 1and1.com and they want all users to upgrade to PHP 5.4 and soon will no longer support PHP4. I have no idea if this is what NOF9 utilizes.
They will perform this upgrade soon and automatically but I don't know if my webpages will be affected by this change.
Does anyone know? I also own NOF 10,11 and 12 if that helps
