Line 114 of the
slideshare.php file, which reads
causes an error reading
First argument is expected to be a valid callback, 'SlideShare_Admin::add_config_page' was given
This error is logical, considering the
add_config_page() method does not exist in
SlideShare_Admin nor in
Yoast_Plugin_Admin class, line 14 actually does what the above line was intended to do.
add_action( 'admin_menu', array(&$this, 'register_settings_page') );
So I commented out line 114 in
slideshare.php and it's no longer broken.
I hope this is resolved in the next maintenance version.
