my code

and the header file on all my pages

while($info = mysql_fetch_array( $check )) 
while($row = mysql_fetch_assoc($in))
while ($row2 = mysql_fetch_assoc($in2))

}

[ratcateme]

have a look at the output page with the error

output is happening on line 16

now looking at your code i think line 16 is

if ($pass != $info['password'])

now that makes no output unless $pass or $info['password'] is not set and it looks like both are set.

really the only advice i can offer is check your output to see if there is anything else.

line 16 is to be exact "<?php"

You CAN NOT echo or output ANYTHING to the browser, even white space!

 

You MUST create your Cookie BEFORE you do that!

 

You may want to set your cookie like this (where I changed the path location):

 

setcookie(ID_my_site, $_POST['username'], $hour, "/", "weew.com");
