I just installed it here;
http://abbottdavid.no-ip.info/guestbook let me know if it works.I had to change the permissions on
data,temp,and config.php
Code:
chmod 777 "dir or filename"
That was all on that link you had,I am now changing the permissions back if it will still work.I need to do some more searching don't like to have to 777 something,good luck
