| <h1>Upgrading from 1.4.0 to 1.4.1</h1> | |
| <p class="important"><strong>Note:</strong> 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.</p> | |
| <p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p> | |
| <h2>Step 1: Update your Code Igniter files</h2> | |
| <p>Replace the following directories in your "system" folder with the new versions:</p> | |
| <p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p> | |
| <ul> | |
| <li>codeigniter</li> | |
| <li>drivers</li> | |
| <li>helpers</li> | |
| <li>libraries</li> | |
| </ul> | |
| <h2>Step 2: Update your config.php file</h2> | |
| <p>Open your <dfn>application/config/config.php</dfn> file and add this new item:</p> | |
| <pre> | |
| /* | |
| |-------------------------------------------------------------------------- | |
| | 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. | |
| | | |
| */ | |
| $config['compress_output'] = FALSE; | |
| </pre> | |
| <h2>Step 3: Rename an Autoload Item</h2> | |
| <p>Open the following file: <dfn>application/config/autoload.php</dfn></p> | |
| <p>Find this array item:</p> | |
| <code>$autoload['core'] = array();</code> | |
| <p>And rename it to this:</p> | |
| <code>$autoload['libraries'] = array();</code> | |
| <p>This change was made to improve clarity since some users were not sure that their own libraries could be auto-loaded.</p> | |
| <h2>Step 4: Update your user guide</h2> | |
| <p>Please also replace your local copy of the user guide with the new version.</p> | |
