Well, clearly '../' is a string (str), and page must be a list. But
without knowing your web framework it's hard to be sure what's going
on.

My guess is that form.getvalue() is returning a list of form elements
with that name, so you have a list with one element in it. But check
your documentation to be sure.

Since this changed when you changed hosts, it may mean you now have a
completely different framework. Possibly you can configure this.
Alternatively, it may simply be a different version of the same
system. It's hard to know just based on this, though.
