The FREEBitcoin and Altcoin Wallets plugin can be installed and updated via wordpress.org.
The wallet adapter extensions can be downloaded from this site as .zip files. Please go to Plugins → Add New → Upload Plugin to install or update your wallet adapters.
If you are a premium member, your activation code gives you access to updates for the installed wallet adapter extensions and app extensions. Go to Settings → Bitcoin & Altcoin Wallets → Updates. Enter your activation code, and hit Save Changes. Any updates to the plugin extensions will now appear in the Plugins admin screen.
The plugin functions normally without the activation code. The code is required only for retrieving updates information.
