I though Following was fixed. Why can I still not see my Followers?
Too many blog owners, and readers, do not realise the significance of the many domains used by Blogger / Google. For Following, the relevant domain is "googleusercontent.com".
Any browser and computer, where the Followers gadget still does not show up, after clearing cache, cookies, and sessions, then restarting the browser in question, needs to be carefully examined for any popup or script filter. Any script filter, that does not permit "googleusercontent.com", will completely prevent the Followers gadget from displaying. And the "break out" Followers window will likewise be blocked by any popup window filter that does not permit "googleusercontent.com".
Check your layered security components - both in the browser(s) that you use, and on your computer. Make sure that "googleusercontent.com" is fully trusted, if you want full functionality from Following - both in the blog display, and from your dashboard.
