There is a quick and easy workaround provided by the power of the lovely language that is PHP, and I've included it below.
PHP Code:
$directory = "#DIRECTORY#";
$dir_hand = opendir($directory);
while (($file = readdir($dir_hand)) !== false)
{
chmod($directory . '/' . $file, 0766);
}
Just replace #DIRECTORY# with the name of the directory in question. Note, though, that this will change the permissions of every file in the specified folder to 766. I hope I've helped, but if you need a more specific and fine-tuned script, just let me know...
