Hi Chris,

Your problem will be that any upgrade in from 4.1 could result in
problems - e.g. register globals being turned on/off by default etc.

See : http://uk2.php.net/releases/4_2_0.php - so you may need to edit
php.ini ...

And http://uk2.php.net/releases/4_4_0.php


I'd probably upgrade to 4.4.0, as i think upgrading to 5.X may be too
painful (i.e. people phone up saying their site no longer works).

If possible, it might be preferable to use a different server for php
5.X?

thanks
David.
