 * thank you very much to both for the response,
    as [@krzyc](https://wordpress.org/support/users/krzyc/)
   suggested downgrading class-wc-cache-helper.php solves the problem. For clarification
   and to make the things easy to others:
 * *backup the file said:
    “wp-content/plugins/woocommerce/includes/class-wc-cache-
   helper.php”
 * Edit the file and cut the line 161 [“add_filter( ‘nocache_headers’, array( __CLASS__,‘
   set_nocache_constants’ ) );”] and paste on line 24 after [“add_action( ‘wp’, 
   array( __CLASS__, ‘prevent_caching’ ) );”]
 * tested again following the steps i described before and the problem disappeared.
   
   [@mikejolley](https://wordpress.org/support/users/mikejolley/) ty very much for

   i just cleared the caches, didnt deactivated this plugin. again thx to both for
   your help.
