if (!isset($_SESSION)) {
session_start();
}
to:
@session_start();
I am having the same problem. I tried this solution and it doesn't work. I cleared the browser/Firefox cache - closed the tab and tried fresh. The first 5-lines of my "helper_PHP.php" file looks like:
<?php require_once( "HelperGroupsRulesPHP.php" ); ?>
<?php require_once( "Mail_PHP.php" ); ?>
<?php
@session_start();
$WA_Auth_Separator = "|§|";
