Also: The plugin doesn't work great under https. I get an error displayed next to the Facebook Like button after it's clicked. I think it might be a callback error of some kind.
Here are some other things I noticed that I don't really like:
- If the option for having Like-Button-Plugin-For-Wordpres on pages is unchecked, there is still code added in the header and the button for adding the shortcode shows up in the editor.
- The shortcode doesn't work. This particular site runs 2.7 MU, yes spare me the details about upgrading, we're doing that soon. The plugin claims to work with 2.7.x but I don't know if it's MU making trouble here or if it's just not working properly under 2.7? This is the error I'm getting:
Fatal error: Call to undefined function esc_attr() in /xxx/xxxx/public_html/wp-content/plugins/like-button-plugin-for-wordpress/include/gb_shortcode.php on line 64
I also tried adding the fb-like button manually to the https pages and it didn't work either which leads me to believe it's not the plugin's fault.
Any ideas how to get it to work on https pages?
