If you're not allowed to open that file, it's very likely you're also not allowed to change the permissions. Check the return code of chmod: 
chmod(0777,$currentlog) or die "Can't change permissions: $!"

As noted above there is almost no reason to do the chmod at all: unless you've got a very strange system administrator, you won't be able to change what you can't read.
