Theme Update from version 6.0 to the latest version

It's simple to update your theme. At first, please download the latest version theme via your Themeforest account's download section then go to your WP Dashboard > Appearance > Themes > delete the Avas theme then install the newly downloaded theme.

There is another way to update the theme without download and delete the theme. You just need to download the Envato Market plugin and configure it accordingly. Please check the link here for the plugin and details.
