Botones añadir/restar carrito vacios

[Eutanasio]

Buenas, hace ya tiempo que me desaparecieron los símbolos + y - para añadir o restar productos al carrito. Alguien sabe cómo recuperarlos?

It is because of your broken CSS. Not broken exactly but your stylesheet don't have content for plus and minus sign so clear cache once and disable CCC to check if it is loading the content in normal mode, if not then restore the global.css file in your theme.

Oook, seems like all "Font Awesome" codes on global.css are missing as you may see on thins fragment:
 

.icon-camera-retro:before {
  content: ""; }

.icon-key:before {
  content: ""; }

.icon-gears:before,
.icon-cogs:before {
  content: ""; }

.icon-comments:before {
  content: ""; }

.icon-thumbs-o-up:before, .icon-thumbs-up-alt:before {
  content: ""; }

.icon-thumbs-o-down:before, .icon-thumbs-down-alt:before {
  content: ""; }

.icon-star-half:before {
  content: ""; }

How could this happen? I'm just going to copy/paste it from another clean global.css
Thank you anyway!
