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.
