I tried using the code you both mentioned in this post : http://www.kriesi.at/support/topic/product-button-hover-weiterlesen-show-details
The first code - Dude gave, made the product images disappear, leaving just the descriptions.
The second code, Bikul used, made my entire site disappear... so weird.
Any ideas as to how to fix this? I don't just want to get rid of the Add to cart" / "Show Details" text, I also want to get rid of the grey bar under the text when you hover.
