  • I have this plugin and it was working fine but suddenly i have this error:

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘Facebook_Like_And_Comment’ does not have a method ‘facebook_like_add_meta’ in /home/zywetrupy/domains/strefawalkingdead.pl/public_html/wp-includes/plugin.php on line 406
