Thanks for your quick reply!
I am sorry, but I think I did not explain well.
I have installed in my theme de WPML plugin, but when I have changed this:
$translations = array(
‘adding_to_cart’ => esc_html__(‘Processing’, ‘basel’),
‘added_to_cart’ => esc_html__(‘Product was successfully added to your Shopping bag.’, ‘basel’),
‘continue_shopping’ => esc_html__(‘Continue shopping’, ‘basel’),
‘view_cart’ => esc_html__(‘View Shopping bag‘, ‘basel’),
in the function.php, as you recommended in another topic, this string is not recognized by WMPL.
The string found is View Cart instead View Shopping bag, and if I translate it, the translation is not effective.
What about the points 1 and 2 from the previous chat? 
Thanks!!!
Estefanía.
