Upgrading from 2.1.0 to 2.1.1

+

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.

+
+
+
+

Step 2: Replace config/mimes.php

+

This config file has been updated to contain more user mime-types, please copy +it to _application/config/mimes.php*.

+
+
+

Step 3: Update your IP address tables

+

This upgrade adds support for IPv6 IP addresses. In order to store them, you need +to enlarge your ip_address columns to 45 characters. For example, CodeIgniter’s +session table will need to change

+
ALTER TABLE ci_sessions CHANGE ip_address ip_address varchar(45) default '0' NOT NULL
+
+
