I found the following on my friend Alison's blog
The easy fix is:
Comment Placement - You have to untick the radio button next to Embedded Comments and select 'Pop Up' instead.
This will fix it and will allow people to see your blog properly and leave comments. Hope this helps anyone having the same problems. However, this will only fix the issue on your own blog, you can't change what you see on others blogs obviously, and this could affect quite a few blogs.
I really appreciate it that you take the time to look at my blog and leave such lovely comments. Thank you each and every one of you. Hugs,
