MM_Username

I'm working to develop an app %26amp; my login function no longer works.?The MM_Username is not being passed between pages.?I've looked at other posts here on this forum, but nothing seems to work.?I have a remote server through GoDaddy; my php.ini file has the below:

register_globals = off
allow_url_fopen = off

expose_php = Off
max_input_time = 60
variables_order = ''EGPCS''
extension_dir = ./
upload_tmp_dir = /tmp
precision = 12
SMTP = relay-hosting.secureserver.net
url_rewriter.tags = ''a=href,area=href,frame=src,input=src,form=,fieldset=''

[Zend]
zend_extension=/usr/local/zo/ZendExtensionManager.so
zend_extension=/usr/local/zo/4_3/ZendOptimizer.so

Here's the code on my login page:

if (!isset($_SESSION)) {
?session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
?$_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['username'])) {
?$loginUsername=$_POST['username'];
?$password=$_POST['password'];
?$MM_fldUserAuthorization = ''usr_pfl_perms'';
?$MM_redirectLoginSuccess = ''log_in_thank_you.php'';
?$MM_redirectLoginFailed = ''log_in_unsuccesful.php'';
?$MM_redirecttoReferrer = false;
?mysql_select_db($database_mySQL, $mySQL);

I know my software is writing the session start();.

Any ideas?

Many thanks.

If that's all the PHP code on your login page, part of it is missing. I would suggest starting with a clean page.
