I updated my website to 3.9. I then got this Fatal error: Call to undefined function wp_register_plugin_realpath() in /home/content/14/10816314/html/wp-settings.php on line 213
I called hosting company GoDaddy and they had me rename all the plugins. And I still can't access my site.
I don't know much about wordpress. I need my site ASAP. I need HELP.
