Index Notification error

Seeing an Index Noticiation error on tt-sidebar-login.php that shows up on the normal wp login page.

Yes I know it’s only a notice but a real pain when developing a new site 🙂

Here’s a patch

Index: tt-sidebar-login.php

 function handle_login_failure($username){
 	// check what page the login attempt is coming from
   	global $current_error;
-	$referrer = $_SERVER['HTTP_REFERER'];
+	$referrer = isset($_SERVER['HTTP_REFERER']) ? $_SERVER['HTTP_REFERER'] : '';

 	if ( !empty($referrer) && !strstr($referrer,'wp-login') && !strstr($referrer,'wp-admin') ) {
 		wp_redirect(home_url() . '/?login=failed&errcode='.$current_error );

Contact me if you would like me to send you the patch file or give me temp access to your svn and I’ll patch for you.
