I think I finally fixed the comments on this blog and I'm now getting emails when someone comments. Hopefully this will work for everyone. There were two people from before that it didn't work for and now maybe it will. Fingers crossed.
Thank you Mary Anne at Magpie's Mumblings who posted a link to where to find a solution. Go here.
I had to do it twice but it seems to be working now. I then received an email that asked me if I wanted to subscribe to comments on this blog and I did what it said and now all is well.
