</code></p>
96 <h2>Step

</h2>
97 <p>Make the following changes to your application/config/database.php file:
</p>
98 <p>Add the following variable above the database configuration options, with
<dfn>$active_group
</dfn></p>
99 <p><code>$active_record = TRUE;
</code></p>
100 <p>Remove the following from your database configuration options
</p>
101 <p><code>$db['default']['active_r'] = TRUE;

102 <p>Add the following to your database configuration options
</p>
103 <p><code>$db['default']['char_set'] =
"utf8
";
<br />
104 $db['default']['dbcollat'] =
"utf8_general_ci
";
