I dont know why I'm having this error:

> 
> Warning: session\_start(): Cannot send session cache limiter - headers
>  already sent (output started at
>  /home/jogarspy/public\_html/index.php:2) in
>  /home/jogarspy/public\_html/core/init.php on line 3
> 
> 
> 

In my `init.php` there are just one `session_start();`

How can I fix it?
