Symptoms

Customer with UX1 MP version higher than UX1MP-6.4.1142 where the function to remove all was introduced tries to remove all items from the cart after adding one more products and click the Clear cart link in 'UX1 Marketplace > Cart > Clear Cart'.

But the 'REMOVE ALL' button is not shown:

Cause

The reason is the changes in a skin css. The used custom skin has an instruction display: none !important to hide all .btn-danger elements. So the 'Remove all' button having such class is hidden as well.

There is no ability to check who the editor of the custom skin was.

Resolution

Customer need to remove this instruction, or introduce a more customized selector.
