 * I put `<?php wp_login(); ?>` in my template header, and I am getting this error
   message:
 *     ```
       Warning: Missing argument 1 for wp_login() in /home/blueribb/public_html/wp-includes/pluggable.php on line 170
   
       Warning: Missing argument 2 for wp_login() in /home/blueribb/public_html/wp-includes/pluggable.php on line 170
       ```
   
 * Here is the function itself, starting at line 170:
 *     ```
       function wp_login($username, $password, $already_md5 = false) {
       	global $wpdb, $error;
   
       	if ( '' == $username )
       		return false;
   
       	if ( '' == $password ) {
       		$error = __('<strong>ERROR</strong>: The password field is empty.');
       		return false;
       	}
   
       	$login = get_userdatabylogin($username);
       	//$login = $wpdb->get_row("SELECT ID, user_login, user_pass FROM $wpdb->users WHERE user_login = '$username'");
   
       	if (!$login) {
       		$error = __('<strong>ERROR</strong>: Invalid username.');
       		return false;
       	} else {
       		// If the password is already_md5, it has been double hashed.
       		// Otherwise, it is plain text.
       		if ( ($already_md5 && md5($login->user_pass) == $password) || ($login->user_login == $username && $login->user_pass == md5($password)) ) {
       			return true;
       		} else {
       			$error = __('<strong>ERROR</strong>: Incorrect password.');
       			$pwd = '';
       			return false;
       		}
       	}
       }
       endif;
       ```
   
 * Any thoughts as to why I’m getting this error? I put the function call for wp_register
   right before that, and it comes out just fine.
 * Thx.

 * I discovered that `<?php wp_loginout(); ?>` worked just fine. Odd, since the 
   function “wp_login” is defined and works in the Kubrick theme, on the exact same
   blog…maybe something different about my theme??….but hey, it works now, so I’m
   good.
 * (And for the record, everything works lots better when you turn on “anyone can
   register” in Admin >> Options >> General. 😛 )
