Please upgrade to 2.1.x here.
The 2.0 branch is no longer being updated.
My hosting company tells me the following:
"We are only a windows host so I`ll so we can`t move you to an apache machine. Looking at their site, I don`t think this software works on a windows server. You will need to contact them to verify this and maybe ask for proper install instructions for a windows server."
Can Vanilla run on a windows host, if so, what do I need to do to make that happen?
