To install the updated version, you need to first re-download the item from CodeCanyon and copy the new files on your web server. After that, run the same installation process as originally done. Note that you can keep your database intact with all of the data (you don’t have to delete and re-create it again). If you want the database to stay as it is, just don’t run uninstallation of the previous version.

If you want to feel more safe, you can always install the new version under a different directory (with the old one still working) and test it before finally switching.

Keeping current configuration and settings after update
There are some files and directories you can keep on your server when updating, so that your configuration, application settings and uploaded avatars stay intact in the new version. For that, upload everything, but those items:

• /php/config/parameters.php
  (stores main configuration and database settings),
• /php/config/app.settings.php
  (stores settings from the Settings tab of the administration panel),
• /upload
  (stores your custom avatars).

• Open the livechat\php\config\app.settings.php file.
• Find the installed=1 line and change it to installed= (nothing after the equal sign).
• Save the file.
• Open the livechat\php\config\parameters.php file.
• Find the 'superPass' => 'yourpass', and change it to 'superPass' => '',
• Save the file.
• Visit the livechat/php/app.php?install URL in your browser and the installation wizard will be displayed, where you can set the password again.

All of the original JavaScript files are available in the livechat/js subdirectories. To use non-minified JavaScript files, please follow to livechat/php/config/config.php and change the following line:

After that the application will load non-minified sources and your JavaScript code changes will be visible in the browser.
