Google Plus One script has quit working, now returns red flag

[slobjones]

Here's the Google Plus One script I've been using on my wordpress blog:


<g:plusone a href="<?php echo urlencode(get_permalink($post->ID)); ?>"></g:plusone>

Worked fine for site visitors until it didn't. Now it's returning a red Plus One warning button with a bunch of suggestions to correct the error, none of which apply.

Does anyone have a Plus One script that will work consistently with wordpress? I don't want to use a plugin.

Thanks.

Try putting the javascript before the body tag.

Try putting the javascript before the body tag.
Assuming that that is not now the case, how to explain that it was working in its current location?
