Upgrading from 1.4.0 to 1.4.1

+
+

Note

+

The instructions on this page assume you are running version +1.4.0. If you have not upgraded to that version please do so first.

+
+

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 the following directories in your “system” folder with the new +versions:

+
+

Note

+

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

+
+
    +
  • codeigniter
    • +
  • drivers
    • +
  • helpers
    • +
  • libraries
    • +
+
+
+

Step 2: Update your config.php file

+

Open your application/config/config.php file and add this new item:

+
/*
+|--------------------------------------------------------------------------
+| Output Compression
+|--------------------------------------------------------------------------
+|
+| Enables Gzip output compression for faster page loads.  When enabled,
+| the output class will test whether your server supports Gzip.
+| Even if it does, however, not all browsers support compression
+| so enable only if you are reasonably sure your visitors can handle it.
+|
+| VERY IMPORTANT:  If you are getting a blank page when compression is enabled it
+| means you are prematurely outputting something to your browser. It could
+| even be a line of whitespace at the end of one of your scripts.  For
+| compression to work, nothing can be sent before the output buffer is called
+| by the output class.  Do not "echo" any values with compression enabled.
+|
+*/
+$config['compress_output'] = FALSE;
+
+
+
+
+

Step 3: Rename an Autoload Item

+

Open the following file: application/config/autoload.php

+

Find this array item:

+
$autoload['core'] = array();
+
+
+

And rename it to this:

+
$autoload['libraries'] = array();
+
+
+

This change was made to improve clarity since some users were not sure +that their own libraries could be auto-loaded.

+
+
+

Step 4: Update your user guide

+

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