PHP is dumping out an error message (the undefined index) to the browser so when you are attempting to redirect you are getting the second message. You cannot output anything to the browser, including error messages like this, before using the header() function.

Fix the undefined index message and your redirection might work.

The problem?

Notice: Undefined index: login in /Applications/MAMP/htdocs/realestate/includes/session.php on line 23

You are using an undefined index called "login" in an array (probably $_SESSION based on the discussion here) on line 23 of the script which is named "session.php" located in the path shown.

If the index is not set yet in that array, or if the array is not yet set, you are going to get an error message, which is indeed what is happening.
