Paypal IPN return Error

[Guest nthrusse]

I think I have done everything right.. But I get this error when paypal tries to rerurn to my site..

Warning: fopen(/2006-Jun-09.log): failed to open stream: Permission denied in /homepages/5/d159930759/htdocs/includes/content/confirmed.inc.php on line 273

can't open file

This is line 273 from the confirmed.inc.php

$today = date("Y-M-d");

$myFile = "/homepages/5/d159930759/htdocs/".date("Y-M-d").".log";

$fh = fopen($myFile, 'abcloggerhead') or die("can't open file"); -------line 273

$stringData = date("[Y/M/d, G:i:s] ").$msg."\n";

fwrite($fh, $stringData);

fclose($fh);

the file is on the root called abcloggerhead it has 777 permissions

Ideas anyone?
