Upgrading from 1.6.1 to 1.6.2

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 these files and directories in your “system” folder with the new versions:

  • system/codeigniter
  • system/database
  • system/helpers
  • system/language
  • system/libraries


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

Step 2: Encryption Key

If you are using sessions, open up application/config/config.php and verify you’ve set an encryption key.

Step 3: Constants File

Copy /application/config/constants.php to your installation, and modify if necessary.

Step 4: Mimes File

Replace /application/config/mimes.php with the dowloaded version. If you’ve added custom mime types, you’ll need to re-add them.

Step 5: Update your user guide

Please also replace your local copy of the user guide with the new version.
