Thanks Jason, well I'm not actually using powerCMS I just used the admin table structure, it's important for me to integrate PowerMessenger into my existing CMS and have removed the original security from the PowerMessenger install before rebuilding it with Security Assist.
After digging around a bit more the problem I have is that I'm losing the session data when linking to pages in a different folder, everything seems fine on my localhost WAMP setup, but not on the live server. I realise this might not be an issue related to the WA products, but wondered if you had any ideas as to how this is happening?
