Hello,
Go to Appearance > Install Plugins and try updating from there.
2- If the automatic update does not work, update manually:
3- Download the latest version from your ThemeForest account.
Here is the URL to download: https://xtemos.com/my-account/
Navigate to Plugins, deactivate WPBakery, and then delete it (you will see the “Delete” option after deactivating).
Upload the plugin manually by going to Plugins > Add New > Upload Plugin, and select the archive from theme/inc/plugins/js_composer
.
Install and activate the plugin.
Best Regards,
