I suggest using the built-in WordPress plugin update feature, but to manually upgrade, follow these instructions:
1. Deactivate the plugin in the WordPress admin menu.
2. Delete the existing tag-cloud.php file from the /wp-content/plugins folder.
3. Upload the tag_cloud folder to the /wp-content/plugins/ directory.
4. Activate Configurable Tag Cloud through the 'Plugins' menu in WordPress and add the widget to your sidebar.
5. (Optional) Add ctc() template tag to your theme. Can be configured either via the Options menu, or via parameters in the template tag.
