Hi again!!!!
One problem fixed (by the moment), I explain myself:
Endpoint Woocommerce:
……com/order-pay/?basel_sidebar=twitter
When the theme was updated, a sidebar Name Twitter was created, and I did not realize of that, because I have not used sidebars in my website!
This trouble maybe occurs to other buyers…. Here is the solution: delete that sidebar 🙂
Regarding the change of CART to BASKET, there is a plugin that when is inactive, the problem is fixed.
But I need that plugin, so I have to contact to developers.
So, thanks a lot for your help!!!!
Nice day!
Estefanía.
