On any Stack Exchange network site, I am having issues
retrieving my notifications (done by clicking the Stack Exchange
logo -> Notifications).  It displays an error with an option to
dismiss. It's been occurring for around 2 years. There are no
trace statements outputted to console either.  enter image
description here   Okay I did a bit of investigating, and the
success callback on the ajax request for the url
http://<siteurl>/notices/genuwine is never being hit.  v =
function (b, a, e, c, f) {     var d = b.attr("id");     if
(u[d]) w();     else {         u[d] = !0;         var g =
function () {             u[d] = !1;
StackExchange.helpers.showErrorPopup($(".seContainer"), "An
error occurred while loading - please try again.")
type: "GET",             url: a,             dataType: e,
success: function (a) {                 u[d] = !1; // NEVER
ENTERS THIS LINE                 a && (0 < a.length || f) ? c(b,
a) : g()             error: g,             complete: function ()
