[ec-cube cmf in localhost Warning ]
<p>When I run my program in localhost I get this error:</p>

<pre><code>ec-cube cmf in localhost 
Warning : Unknown: function 'NULL' not found or invalid function name in Unknown on line 0
</code></pre>

<p>I only have this path folder:</p>

<p>C:\xampp\htdocs\project\data\config\</p>

<p>and the contents of config.php is: </p>

<pre><code>&lt;?php
define ('ECCUBE_INSTALL', 'ON');
define ('HTTP_URL', 'http://localhost/project/');
define ('HTTPS_URL', 'http://localhost/project/');
define ('ROOT_URLPATH', '/project/');
define ('DOMAIN_NAME', '');
define ('DB_TYPE', 'mysql');
define ('DB_USER', 'root');
define ('DB_PASSWORD', '');
define ('DB_SERVER', '127.0.0.1');
define ('DB_NAME', 'project');
define ('DB_PORT', '');
define ('ADMIN_DIR', 'admin/');
define ('ADMIN_FORCE_SSL', FALSE);
define ('ADMIN_ALLOW_HOSTS', 'a:0:{}');
define ('AUTH_MAGIC', 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
define ('PASSWORD_HASH_ALGOS', 'xxx');
?&gt;
</code></pre>

<p>This problem pops up only when I set or change the password. Please share some idea to fix this warning.</p>
