I don't see why this should work at all given the error output. You need to resolve the errors given such as "CodeTaskFactory."

YOU get to fix that and the other errors. Sometimes folk think this is a simple fix, sometimes it is but right there in the error is why.

Let me ask why do this at all? If you want to run a website there are much easier ways to put together a site.
