Issue on PHP Website

HI We have a website that was functioning perfectly and was moved to a new server and has had PHP upgraded so there are a couple of things that need fixing due to the php upgrade I was able to add the missing database entries too – so that anyone doing the induction now will be allocated a new unique Sequence number that doesn’t overlap with the missing users. There are a couple of issues that do still need sorting out: 1. PHP scripting doesn’t appear to function properly - in particular the [login to view URL] under the control folder doesn’t redirect the user to the accounts webpage after a successful registration is added to the database (and an email sent), so it appears that someone hasn’t registered when it was actually successful. 2. Also the error checking on the [login to view URL] doesn’t appear to function properly and doesn’t report what the issue was to the user. So for example if someone successfully registered (as in issue 1 above), then they are presented with a blank page, so will likely try to register again using the same email address, but they wont receive the error message that the email address already exists in the database.
