unlink error - don't know how to fix it

I could be wrong, but your error message doesn't indicate that you have a problem with permissions, it says http doesn't allow unlink, which is I believe the error when you do something like unlink('http://mysite.com/myfile') - which you can't do. You have to provide unlink() a link relative to your local filesystem or have one of the wrappers in PHP that allows some other functionality (but HTTP isn't ever an option with unlink), so make sure of that before you worry about chmod.
