Just a quick wee post from me today.
Yesterday my blog wasnt playing nicely, and everytime I tried to access a post from the main page to read comments etc, it just went blank.
I googled blogger issues, and it seems that they have altered the 'threading' in embedded comments yesterday, and many other bloggers were having the same problem.
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.
Edited to add: This will only fix the issue on your own blog, you cant change what you see on others blogs obviously, and this could affect quite a few blogs :(
