There are 2 options for how to update your theme.
Option 1 (automatic):
Install recommended Envato Market plugin via Appearance -> Install plugins. Generate an Envato API Personal Token, paste the token, and save changes. When the theme has a new update, you will see the notification and can update it on the fly. Read more about how this process works at envato.com
To generate an API token click on the Generate an Envato API Personal Token link in your dashboard menu. If you’re already logged into your Envato account you’ll be taken to the screen below (otherwise you will be prompted to log in first before being redirected to this page). On this screen give the permissions to Envato Market plugin (Envato sites, the ability to download your items, a list of your purchases, and verification of your purchases). Next, give your token a name, check the box that you have read and agree to the terms and then click the green button to create your token.
After successful completion, copy the generated token and save it to a safe place. Envato doesn’t store your token for you. Confirm by clicking the white button.
Paste token, and save changes.
Option 2 (manual, using FTP):
- Extract the theme package that you downloaded from Themeforest and unzip the estand.zip file.
- Connect to your server via FTP and navigate to /WP-CONTENT/THEMES folder of your WordPress installation, replace the existing folder named estand with the unzipped folder.
