Ah ok no problem. Seems a bit of a strange setup but what woprks workd I never noticed there was a php.ini file there.
The default rearlly should be "Europe/London" rather than GMT as this isnt recognised by PHP.
Does this not open a security risk having the full settings avialble to get by simply typing in
http://www.domain.com/php.ini ? shouldent this be under a non public directory.
