upgrade to php5 include not working

[tombstone]

I have this include statement...
if($_POST['submit'] && !$_SESSION['loggedin'])
{
include("./checklogin.php");
}


it worked under php 4.whatever I upgrade to php5 and it stopped working. I know it is making it to the IF statement I did an echo in there and that was fine.

Thanks
Tom

What error message do you get? (If none, have you tried setting error_reporting(E_ALL); before that code gets executed?)
