I have two php pages one a register page and the other a sign in page. The server is running php 5 as well.
Link to these two pages
http://www.steveoatman.me/gallery/sign_in.php
http://www.steveoatman.me/gallery/reg_form.php
When I sign in or register I receive an error
Warning: Cannot modify header information - headers already sent by (output started at /home/soatman/public_html/gallery/sign_in.php:2) in /home/soatman/public_html/gallery/sign_in.php on line 77
My problem is with the head() tag and the session_start() tag. From my research I need to have the session_start() at the very first line in the script. Okay I understand this and moved it to the very first line.
I moved the session_start() tag to the top of the page. It works fine in Firefox but IE6 it is just showing a blank screen after you submit the form. Strange if I refresh the page at this point it redirects to the correct page and you are logged in.
I believe this is a browser problem but can not find a way around this or a fix for this problem. This is a simple register and sign in script, so I am very confused. This same script did work about four months ago when I was in college.
This is a copy of just the sign in page at this time I can include the register page script as well if needed.
<?php session_start(); ?>
<?php ob_start(); //starts the output buffering ?>
