Looks like mine is a different situation. I already had SecurityAssist 2.0.2 installed. I did proceed with the rest of the steps. However, I still get the error message. The error comes up when I try to submit the registration.
Fatal error: Call to undefined function wavalidateunique() in D:\wwwroot\hopeoftheworld.org\www\registration.php on line 14
I've attached the registration file.
