error when trying to log into admin after changing admin name

I have just made changes to my admin/includes/configue.php file and change the admin name to a new security name which is the same as what I change in the configue file. I now cannot log into my admin folder, I get the following message,

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/content/#####/html/testsec/includes/configure.php:1) in /home/content/#####/html/includes/functions/sessions.php on line 108

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/content/#####/html/testsec/includes/configure.php:1) in /home/content/#####/html/includes/functions/sessions.php on line 108

Warning: Cannot modify header information - headers already sent by (output started at /home/content/#####/html/testsec/includes/configure.php:1) in /home/content/#####/html/testsec/includes/functions/

I have change to new admin same in the above example for security reasons. My website seems to be working ok at this time.

I am using Zen-Cart 1.3.8

Thanks for your help

You probably have a blank line or space, or some other invalid character on line 1 of that file.

I am having the same problem:

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/content/xxx/includes/configure.php:1) in /home/content/xxx/includes/functions/sessions.php on line 108

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/content/xxx/includes/configure.php:1) in /home/content/xxx/includes/functions/sessions.php on line 108

Warning: Cannot modify header information - headers already sent by (output started at /home/content/xxx/adminkej55/includes/configure.php:1) in /home/content/xxx/includes/init_includes/init_templates.php on line 36

I have confirmed several times that there is no blank line or characters in confirgure.php at line 1. Nothing before <?php** and nothing after **?>

Just one other possible point -- my site was upgraded to PHP 5 at the same basic time. Would this better explain the problem?

PHP5 should have nothing to do with it.

What editor did you use to edit the configure.php file? It sounds like you've got hidden characters at the beginning of the file, which is a classic indication of using an editor that's set to UTF8-With-BOM mode instead of UTF8-without-BOM or just plain ANSI/text/ascii instead.

Originally I had used MS Expression Web but subsequently I have just used Notepad. Maybe create a new text file and copy into it??

EEKS ... I would NEVER trust an MS application to edit anything on my website. Ever. Way too much crap and unreliable in my experience.

Well, the new text file seemed to do it. Unfortunately MS Expression Web was the default for *.php files so that is why it opened it automatically. Notepad from now on. Thanks!

You'll enjoy Notepad++ better. http://notepad-plus.sf.net
