Solved

Step 1
Installed manually a new version of the theme:
– download from theme forest
– uncompress and rename locally the folder from enfold to enfold_new
– uploaded the folder via FTP to /wp/wp-content/themes
– renamed /wp/wp-content/themes/enfold to /wp/wp-content/themes/enfold-old
– renamed /wp/wp-content/themes/enfold-new to /wp/wp-content/themes/enfold
Now reload the page of the site and the fresh files are loaded.

Step 2
Now there is an issue with the API key, since now it uses tokens.
So, to obtain a token, visit https://build.envato.com/create-token/
Select the following the permissions as explained here https://kriesi.at/documentation/enfold/theme-registration/#toggle-id-5

Step 3
Now the hook wp_body_open is available, since the new header.php file has these lines

	if( function_exists( 'wp_body_open' ) )
	{
		wp_body_open();
	}
	else
	{
		do_action( 'wp_body_open' );
	}
