Question

Answer 1

My first step in a situation like that is usually to check things in the order that will most quickly reduce the number of things left to check. You could almost think of it as doing a binary search for the bug: "Well, the POST parameters look right, so I can rule out everything before the form submission," etc.

That said, if I have a strong feeling that the problem might be in a particular place, I'll check that first.
