The problem is probably this output before the header

    echo"
    <script>
    window.sessionStorage.setItem('valor1', '$qtdQuestoes');
    window.sessionStorage.setItem('valor2', '$tipoRespostaComplet');
    window.sessionStorage.setItem('valor3', '$respostaCorretaComplet');
    window.sessionStorage.setItem('valor4', '$resposta');
    window.sessionStorage.setItem('valor5', '$acerto');
    window.sessionStorage.setItem('valor6', '$nota');
    </script>
    ";
    Header("Location: ../index.php");

Enable and configure error logs accordingly, and you may see that there is a conflict of headers in this section.

Your situation is somewhat unusual because from what I understand does not necessarily have to write something on the screen to the user but you need to write JavaScript to set data in window.sessionStorage . I do not know if I can say this because I am oblivious to what you are doing, but this is more a design problem. I am not referring to the "design" of image / layout / art / illustration, but of logical structure of programming.

Normally, in programming logic, when we come to a crossroads it is because we fail at some logical point in the structure. Think of a way to redesign the logical structure. Otherwise it can also solve, however, by gambiarras. Choose what is most convenient because sometimes a gambiarra is better.
