"I dunno what I was thinking when I just pressed 'Send'".
Anyway, that's how I felt when I pressed the button to connect my blog to Google+ only to find absolutely everything changed including my comments section.
What was I thinking and why didn't I read more closely?
I spent way too long trying to figure out how to revert back to the original blogger profile, thinking that would also revert back to the blogger comments. I did figure out how, but the Google+ comments were still enabled. Grrr. Not only did I still have Google comments, but now I didn't have a Google+ dashboard to work with.
After doing a Bing search and reading a few sites, Eric finally found the answer for me.
(It's really nice to have my System Administrator in house!)
I am posting a screenshot here in case you have done the same thing and feel stuck.
The first thing I had to do was go back to using my Google+ profile. (not the one from Blogger.)
On your blog dashboard - click on the Google+ tab. (See on the left in orange.)
The screen should look like this.
Make sure the check box is UNCHECKED for using Google+ comments. (I circled it in red for you.)
I had actually successfully unlinked my blog from Google+ so that check box was NO WHERE to be found!
When I clicked on the shaded gray area below my photo and name with the blogger symbol (which said link blog to Google+) then the check boxes showed up.
So - your blog must be linked with Google+ in order to have that check box option.
I apologize to my readers for any inconvenience my stupidity has caused you.
Would you help me by leaving a comment so I can confirm I really fixed the problem. (I suppose a lack of comments might be a clue too.)
Anyway, happy blogging and... commenting. :-)
