Warning: session_start()

[Nazish <nazish@xxxxxxx>]

Hi everyone,

I recently uploaded my website files to a server. When I tried to log into
my website, I received these error messages:

*Warning*: session_start()
[function.session-start<http://www.myparcoasis.com/function.session-start>]:
Cannot send session cookie - headers already sent by (output started at
/home2/myparcoa/public_html/index.php:10) in *
/home2/myparcoa/public_html/includes/login_form.php* on line *33*

*Warning*: session_start()

/home2/myparcoa/public_html/includes/login_form.php* on line *36*
*

The website worked fine on the Apache localhost server (I could log in), so
I'm not sure what's wrong with the code which is creating the error on the
online server. Any ideas? I've highlighted the two error lines (31 & 34).
I'd appreciate any insight! Thnx!
