Upgrading from 1.7.1 to 1.7.2

+

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
    • +
  • index.php
    • +
+
+

Note

+

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

+
+
+
+

Step 2: Remove header() from 404 error template

+

If you are using header() in your 404 error template, such as the case +with the default error_404.php template shown below, remove that line +of code.

+
<?php header("HTTP/1.1 404 Not Found"); ?>
+
+
+

404 status headers are now properly handled in the show_404() method +itself.

+
+
+

Step 3: Confirm your system_path

+

In your updated index.php file, confirm that the $system_path variable +is set to your application’s system folder.

+
+
+

Step 4: Update your user guide

+

Please replace your local copy of the user guide with the new version, +including the image files.
