• I’m getting the error on a site running this plugin. I suspect this may be something related to the PHP version. I’m running 5.4 locally where I see the error occurring, but I’m not sure what version is on the live site.

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'addmetawebcapablelinks' not found or invalid function name in /srv/www/erffoedstem/wp-includes/plugin.php on line 505
