Starting next month Blogger.com will only support modern browsers.It is now more important than ever, to be aware of the browser version that you are using.
If you have a problem with Blogger or BlogSpot, maybe involving
- The New Blogger GUI (2011).
- Publishing or reading comments.
- Seeing or Blocking your Followers.
If you're using Internet Explorer, you may also do well to check your "Compatibility View Settings".
Find out what version you are using. From the browser menu, select "Help", then select "About". And, there it is - either in the window, or in a popup (this will vary by browser).
When you know the browser version, verify that it's currently supported - and upgrade if necessary. And when you're asked to provide the browser name and version, copy and paste the browser name, and complete version number, from the display.
