使用会话codeigniter时出错

Question

I have a problem while publishing my site. I have a autentication system using session by codeigniter. When it's run on localhost, its perfect. But when i publish in the server (hosting godaddy), It display this message Severity: Warning

Message: session_start(): Cannot send session cookie - headers already sent by (output started at /home/cristiandelacruz/public_html/crmappsdc/application/config/config.php:1)

Filename: controllers/Login.php

Answer 1

It means you have something output on browser while redirection.

You can do following things:

1) Check which code is printing HTML. And remove it. eg. Spaces, echo or print statements.

2) if this does not work, add ob_start (); at the file beginning. It stores output in buffer and redirection occurs.
