If you have one of our templates installed (or any other template, for that matter) and your comments have suddenly stopped working - you get an error message when trying to click on the comment link in your post footer - let's fix this!
From your blogger dashboard, click the little dropdown arrow you'll see below, and click on "Google+":
Make sure "Automatically share after posting" is unchecked.
Voila! All done! If Google+ comments was the reason your comments weren't working, they should now be fixed.
