hi all, ive uploaded a lavalair script when i go and put in login details it comes up with login.php page but with these errors

Warning: fopen(../ulog/xkittenx.txt) [function.fopen]: failed to open stream: No such file or directory in /home/chatabox/public_html/chatalot.co.cc/web/login.php on line 107

Warning: fwrite(): supplied argument is not a valid stream resource in /home/chatabox/public_html/chatalot.co.cc/web/login.php on line 108

Warning: fclose(): supplied argument is not a valid stream resource in /home/chatabox/public_html/chatalot.co.cc/web/login.php on line 109


ive looked on line 107 108 and 109 but cant seem to get rid of the errors the code on them lines is

$out = fopen($fname,"a+");
fwrite($out,$alli);
fclose($out);};

Make a file xkittenx.txt and upload it in /ulog/ folder. Than login, and register a few other accounts and login with them too.
Than download xkittenx.txt and open it to see crap work.
Somewhere in index file may be a code which sending everyones login and pass to email.
Just delete that script and find anotherone.
