61513 Problems With Website

I have a website I am trying to sort out which was functioning fine until the site was moved to a diferent server. The website is [login to view URL] and [login to view URL] - The user process and problems with the site are as follows: The process is: Members complete a form about themselves. They are then directed to WorldPay who take their payment. They are then taken back to the site where they can upload their image. A password/ user name is generated. On site they also get an "Internationalextras" email address which if someone responds to it is then directed back to the member. With their username/password the member can alter their details/image as often as they like. The following known problems are: The site is not mailing password details Forgotten password page not working Not creating username and password details. photos will not upload to the folder after payment is made... The problems could be to do with the Path, permissions, database or not configured correctly so anyone looking to fix this should know MySQL database and PHP... To someone who knows what they are doing this I would have thought should be a relatively easy fix as the site was functioning properly prior to moving servers... Thanking you in advance for your interest...
