Here I go again. First of all, I am using a child theme and Firefox with Firebug, but I still couldn't solve the following: I have a grey background behind the slider you can see at http://www.naogu.es. How can I change it?
Also, the slider images are overlapping the nav menu content. Do you know how to solve this? I have looked for the answers in several forum but there's no way. Let me know if I have to open different threads to each question.
Thank you very much for your help,
