I have subzero knowledge of Magento, yet I was asked to change just the Caption of the Button place order as the existing Spanish translation confused customers. So I went to locale and changed the text where it said: Hacer un pedido I wrote Completar este pedido.
I uploaded the csv file back,. but I am still seeing "Hacer un pedido". I am afraid to mess with the cache or index or whatever because I have no understanding of the inners of magento, but I have not even modified any php code, just a text of a button. What do I need to do to make the change visible to customers now?
