Starting with KLEO version 4.0, Visual composer will get updates right from your admin panel.
This means that you don't need to wait for a theme update to get Visual composer updated.
Just follow the steps to update Visual Composer plugin:
- Go to WP admin – Appearance - Install plugins.
- Click the Update button next to the Visual composer plugin. It will only appear in the list if an update is actually available.
Re-download the theme from Themeforest. You will find the .zip archive under the main package downloaded from Themeforest under Plugins folder. You can delete the old plugin from WP Admin – Plugins and upload the new .zip file
