You have two options to update Artemis – Multi-purpose WooCommerce WordPress Theme theme:
The easy way is to update the theme via Envato Toolkit plugin – this can be done directly from your Dashboard.
Please navigate to Envato Toolkit page.
Enter your Envato Marketplace Username/Secret API Key on Envato Toolkit and click Save.
The Secret API key can be generated from your Envato account by navigating to Settings – Your Details – API Keys.
Once the credentials are correctly entered, you should see a second tab – called Themes.
Go to this tab, and will be notified if a new theme version is available for download and will be able to update it automatically. Please check the screenshot below for better understanding:
Download again the theme (installer package) from ThemeForest.
Unzip the theme installer .zip file and you’ll obtain artemis-swp theme folder.
Connect to your website via FTP and navigate to [wordpress install directory]/wp-content/themes/.
Copy your new artemis-swp folder over existing folder with the same name, on this location.
