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