I have a page where I do different requests via AJAX, also I have the developer DB and the production DB but the JS is the same. In certain module, if I open it using the developer DB it shows me the response but if I use the production database it shows nothing but not error is displayed. If I use the production DB in any other module it works perfectly. I already checked in the network console and it says that in both cases the request is sent. Here is the JS code:
function consultaAdministradores(id, tipo, btn){
var datos = {
    'id': id,
    'tipo': tipo
  }
  console.log("DATOSSSS");
  console.log(datos);
$.ajax({
  url: '../send/get_AdminEmpresas.php',
  type: 'POST',
  data: datos,
  dataType: 'JSON',
  success: function(res) {
    console.log(" res --------- ");
    console.log(res);
    imprimeAdmins(res);
  }
});
console.log("Se pasó el AJAX");
And in the PHP file I have this:
  $res = $con->consulta($sql);
  if ($res->num_rows > 0 ) {
    $i = 0;
    while ($dato = $res->fetch_assoc()) {
        $administradores[$i] = $dato;
            $i++;
    }
    if ($tipo_page == 'prev') {
     array_multisort($administradores);
    }
    $array = array('status' => "Success", 'administradores' => $administradores, 'id' => $id_page, 'tipo' => $tipo_page);
  }
  else
  {
    $array = array('status' => "Fail", 'message' => 'Sin resultados');
  }
  $json = json_encode($array);
  echo $json;
