I made a simple news update system a few nights ago using dreamweaver.

 

I had a few problems with logging in but all is fine now, or is it?Well it isnt. It seems that once i have logged (whic forwards to broswer to the admin;php page, from here i have links to add_news.php, update_news.php and delete_new.php) when i go to the "add_new.php" page is seems to bring this error up.

 

Notice: A session had already been started - ignoring session_start() in c:\program files\easyphp1-8\www\news update\add_news.php on line 25

 

Warning: Cannot modify header information - headers already sent by (output started at c:\program files\easyphp1-8\www\news update\add_news.php:25) in c:\program files\easyphp1-8\www\news update\add_news.php on line 63

 

Right line 25 shows;

 

<?php

   $isValid = False;

   // Therefore, we know that a user is NOT logged in if that Session variable is blank.
   if (!empty($UserName)) {
