Upgrading from 2.1.4 to 2.2.x

+
+

Note

+

The Encrypt Class now requires the +Mcrypt extension. If you were previously using the Encrypt Class +without Mcrypt, then this is a breaking change. You must install +the Mcrypt extension in order to upgrade. For information on +installing Mcrypt please see the PHP documentation +<http://php.net/manual/en/mcrypt.setup.php>.

+
+

Before performing an update you should take your site offline by +replacing the index.php file with a static one.

+
+

Step 1: Update your CodeIgniter files

+

Replace all files and directories in your “system” folder.

+
+

Note

+

If you have any custom developed files in these folders please +make copies of them first.
