I have been using the code found on pp 371-372 as a low tech way to authenticate pages. Recently, my ISP was bought out and I moved files over to a GoDaddy.com account (Linux Server). After uploading the exact same site, my login system quit working and displays the following errors:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/content/u/s/e/username/html/topics/spring.php:2) in /home/content/u/s/e/username/html/topics/auth.inc.php on line 1

Godaddy sent me the following response:

Thank you for contacting customer support. Unfortunately, you cannot reference php/cgi/perl scripts from Apache, nor can you call *.html and other Apache loading files from the /cgi directory. This is due to our use of S-Box in conjunction with Apache to maintain the stability of our shared servers. All php/cgi/perl scripts are run in S-Box as a contained
environment, so if a cgi application stalls or breaks the environment, all that needs to be done is reset S-Box to resolve the issue. Due to this, any Apache references to php/cgi/perl will fail. This includes .htaccess files, SSI's, and basic script references. The easiest way around most of these issus is to incoporate your html into a php file, therefore running the html inside S-Box, which will then allow you to call php/cgi/perl files.

I checked to be sure my files were ANSI encoded and that they had no spaces above the php begin tag.

Any ideas on how to proceed?

It si because something is being outputted to the browser on line 2 in spring.php.
