Ok so I have figured these issues out.
1. Last week, or the week before I can't remember, I couldn't comment on anyone's posts. I always keep my blogger account "signed in" (Log in page- it says "STAY signed in"). When I unchecked that box, I could comment on people's blog posts. This is very annoying because everytime you want to post a comment you have to sign in.
2. Today's issue- Can't see followers
I played around with the dreaded "Stay signed in box"...AND it worked! In order for you to see your followers, you have to check the "Stay signed in" box.
I see lots of clicking THAT box in our future.
