I recently installed the Google+1 button because everyone else is doing it and if everyone jumped off a bridge, I guess I would too. I noticed someone +1'd one of the posts on my blog(!) but I couldn't tell which one because ALL the posts had a +1 and it seemed odd that someone would +1 each and every one of my posts no matter how good looking I was. This is an error in the standard Google+1 HTML -- it doesn't know which page/post to +1! So if you've tried installing it manually with this code:
Place this tag in your head or just before your close body tagYou'll have to use this instead of the second code:
Place this tag where you want the +1 button to render
<g:plusone expr:href='data:post.url' size='medium'/>The new code will specify that each post will be +1'd instead of the whole blog when you're looking at it from your homepage. You can change the size of your Google+1 button by changing the 'medium' text from the codes here. Options: 'small', 'tall', or delete size='medium' to get the standard button. If you have any questions, let me know in the comments below and I'll try to help the best I can!
