If you have an active subscription, there are a couple of ways you can update your themes and plugins from AudioTheme.
AudioTheme Agent
We recommend using the AudioTheme Agent to install and manage updates for your themes and plugins directly from your WordPress admin panel.
The agent hooks into WordPress’ update process and will let you know when a new release is available so you can update it just like plugins and themes from the WordPress.org directory.
Manual Updates
If you don’t have the AudioTheme Agent installed or have trouble connecting your site, you can update your plugins and themes manually. Log in to your account on AudioTheme.com to download the new release, then upload it in your WordPress admin panel.
Read the instructions for updating a theme manually.
