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 :(
