This plugin adds a Like-Button wherever you want on your blog. Before or after the content as well as a sidebar-widget. And many more!
Extract the zip file and just drop the contents in the
/wp-content/plugins/ directory of your WordPress installation and then activate the Plugin from Plugins page.
Make sure that your template has the
wp_footer(); in its footer.php-file and
wp_header(); in its header.php-file!
After that visit the General-Setting Page on the bottom of the Menu and activate the Like-Button via the first Checkbox. After that you have to generate the Button with the Generator below and define the Position-Settings on the Position-Setting-Tab. Then hit the save button and you're done! All the other pages include different and additional options! Additionally you have to visit the OpenGraph-page and set all the Administrative and Blog-Tags.
Recommendation: it is better to use the XFBML-Version or even provide a valid App-ID if you still use the iFrame Version! Please enter a valid App-ID if you do not already have one! Get an App-ID
