Anyone know how i can reslove this issue, i had a spam bot looking for directorys and found that this error came up many times.. Nothing seems to be wrong with my code so im not to sure what i should do...

 

Thanks for your responces

You have some form of output before you call session_start(). There must not be any form of output before you call session_start().

 

Looking at the error PHP has detected that output has started on line 2 in index.php and your session id is invalid.

 

Post index.php here for use to look at. Make sure you post your code within code tags (

).

hmm weird the onlly thing i have before session_start(); is <?php

 

index looks like below:

<?php
session_start();
require_once("assets/connect.php");
/// rest of login script
?>

 

Starts like that on index,register,lost pass

 

all had the exact same error in the cPanel logs :-\

also just to clarify no html is above that either ...

Umm that code is fine. Looks like your PHP session is is currupt. Try clearing your cookies for your site. Does the error persist?

[MemphiS]

Thanks for the help wildteen.. uhm the errror doesnt persist. Ive had some search bot snooping my directory for different programs.. nothing unusal..blocked the ip of the bot.. just wanted to make sure i clear up this error to stop it coming about again..

 

How do i clear the cookies? Wasnt aware that servers had cookies haha :s

[wildteen88]

No not the server clear your browsers cookies for your site - clearing any cookies set for sessions.

 

if the problem persists have a word with your host.
