 * wp-login and index.php are blank. I checked error logs and see this repeating
 * **PHP FATAL ERROR : Call to undefined function wp_register_plugin_realpath ( )
   in wp-settings.php line 213**
 * // Load active plugins.
    foreach ( wp_get_active_and_valid_plugins() as $plugin){
   wp_register_plugin_realpath( $plugin ); include_once( $plugin ); }

 * One of your plugins is most likely causing this.
 * First start by logging in to your FTP, going into wp-content folder and renaming
   the “plugins” folder to “plugins.old”…then try logging on to the site.
 * If that works, go into the dashboard and click plugins (you’ll see that they’ve
   all been deactivated). Rename your plugins folder back to plugins and one by 
   one, activate them. If the site crashes, that plugin that you just activated 
   is bad.
