Imagem cabeçalho Misty Look

Olá, sou uma anta em css e resolvi customizar meu blog. No entanto, apesar de já ter feito upload de um cabeçalho que tenho, ele nao aparece no blog. Nao sei se as margens que coloquei estao erradas, nao consigo encontrar o problema. Aliás nao sei nem descobrir qual a versão de wp que tenho… 🙁
Alguém pode me ajudar?
