I just noticed that the MyBlogLog comment avatars weren't working in this blog. It seems that Merlinox (the blogger who invented this hack) has either removed or relocated the script we were using to make the avatars appear in our Blogger blogs. So the avatars just weren't appearing at all.
So if you have installed the MyBlogLog comment avatars hack and your avatars do not display, here is the fix:
Find this line in your blog template:
And change the line in red to this instead:
This will link to the script hosted on my server instead, and will ensure your MyBlogLog comment avatars display as normal.
Hope this solves any problems you may have been experiencing as users of this hack!
