My first time here and I need HELP…..

Dear experienced users with WordPress.

I installed the wordpress 2.3.1 and everything went fine, I am trying to convert an english template in to spanish language.

I already installed the new version of *.mo in spanish and everything seems ok, but the problem arises when there are some parts of the end user interface seems in english.

Can you tell me if there is something about wrong about the template or the *.mo file? What do you suggest, to inspect all *.php files to see where are those missing words?

my blog website that I am translating is:

thank you on advance
