signup.php doesn't work on php 4.3.10

Hi Dean,

I've been using your script for almost a year now without problems until now.

I tried to signup to my newsletter here:
http://www.smartselling.biz/index.php

Duplicate emails checks out ok but when you signup for a new email address it sort of "times out" and when I hit refresh I saw this error message:

Warning: Variable passed to each() is not an array or object in /home/smartsel/public_html/mail/signup.php on line 57

Warning: reset(): Passed variable is not an array or object in /home/smartsel/public_html/mail/signup.php on line 123

Warning: Variable passed to each() is not an array or object in /home/smartsel/public_html/mail/signup.php on line 126

This didn't happen to me before until I checked their php version here:
http://www.smartselling.biz/test.php

Its now v4.3.10

The last time I checked it was 4.3.8. I also have other script problems when I upgraded my php version to 4.3.9 from my other server so I think the script needs editing or something.

What do you think is the problem?

Okay, this is a longshot but try removing or adding (toggle it) "www." to the prefix of the URL in your signup form's ACTION element.
