Good morning Nairalanders. i have a problem with my website which did not allow me to log-in to my wordpress panel and also resulting to my site not displaying. I just saw it this this morning and i don't really understand cause i did not alter any code. Here is the error code Fatal error: Call to undefined function wp() in /home/africwap/public_html/wp-blog-header.php on line 14 and here is the code in that particular directory <?php
/**
* Loads the WordPress environment and template.
*
* @package WordPress
*/

if ( !isset($wp_did_header) ) {

$wp_did_header = true;

require_once( dirname(__FILE__) . '/wp-load.php' );

wp();

require_once( ABSPATH . WPINC . '/template-loader.php' );

}

You broke something in your server backend or you have a faulty/expired/unsupported plugin.
