Blank emails

I’ve just setup the security module and everything is working as it should except for the email… seems selecting Activation Email sends the user a blank email no link or code to activate account or “Subscription”, at least in my test environment yet the admin receives the expected confirmation email a user has registered.

Any idea as to why?

NVM I found the answer - man and I searched for hours on google, then bang here it was all along http://www.scriptcase.net/forum/forum/main-category/main-forum/64721-security-sprintf-too-few-arguments
