For the first time that I can recall I received a dangerous site message when I tried to open the blog today. A reader called me as well to report that she was also having trouble logging in. I got in touch with google support. The man who answered said, not to worry, it is not the blog.
Instead, it's an issue with Blogger itself. Since Blogger is pretty much outdated, browsers, such as Chrome, will consider the website as "deceptive". Basically, Blogger currently has outdated certificates and it doesn't meet Google Chrome's requirements.
In fact, you can even go to https://blogger.googleblog.com/, which is a blog created by Google itself and you'll probably find the it's also considered as a "Deceptive site".
I asked him if they were planning on fixing the problem and he didn't know. Told me to send some feedback to the developers. This is troubling to me. Google has a sad and beguiling habit of suddenly cutting the cord on their own platforms, no matter who and how bad it hurts, they did it on Google + and so many other programs. (see: killed by google)
Perhaps the blog will have to go to Wordpress or something and take another shape? This is very troubling, will try to get to the bottom of it.
