Flash shoutbox trouble

i’m using the attached shoutbox ( only flash 8 / php and xml ) - it worked for a long time
now all of a sudden it would only show the date
the name and comment fields are not being written to the xml file
how come ? must have something to do with the php files ( i don’t really know php )
and yes i changed the chmod commands / could it be the new server the site is hosted ?
or do you know of any shoutboxes with php and xml only ?

i appreciate your help
