First of all, posting this once is enough. Second of all, I think the
problem here is actually a lot easier than it would look at first glance :)
I noticed the following error:
Warning: fopen(ssh2.sftp://Resource id #10/[...]): [...]
Now, what you see here is that you suddenly have a "ssh2.sftp://Resource
id #10". This is probably not the domain name you're trying to connect
to, now is it? :) That string typically appears only when you cast a
resource to a string (eg. a mysql-connection, a stream, or whatever).
So, looking at line 79, I would guess that $sftp isn't a string which
tells fopen where to find the file to open, but instead is a resource
which should not be there at all.
