PHP session_start（）; 错误

for some reason my php script stops executing the php code after i state the session_start() action, This problem only occurs when i try to test it on a webserver (it works fine on xampp)

Here's a piece of the code: (Note in only works if i remove the session_start action.)

session_start(); 
//CODE STOPS HERE 
$date = date("Y-m-d"); 

if(isset($_SESSION['username'])) 
{ 
$username = ($_SESSION['username']); 

echo "<div id = 'registratie'> 
<form method='POST' action='register.php'> 


<h1>Registratie formulier</h>

this is the error i am getting: Fatal error: session_start(): Failed to initialize storage module: memcache (path: /tmp) in /home/builder/domains/site-builder.nl/public_html/clients/nm/stagiares/stageproj‌​ectotman/member.php on line 27

Line 27: session_start();

If you are using PHP7.0.0 on xampp you may try the below:

Note: Just search the below in your 'php.ini' file located at 'c:\xampp\php\php.ini' to fix the issue: (chage the value to 1 from 0)
