You have translated the English page, so I will have to roll it back. Sorry to have your work wasted.
Please use the sidebar link to apply for a translator account, after which you will see a new link "Translate this page" which will allow you to update the Spanish page. Usually your translator account is activated with a few hours of applying for it.
My intention is translate the Catalan language.
I guess the problem is always to save a whole page - all translated.
Your account is now approved. You should now be able to see, on pages with translations, a link above the language bar. Follow that and you can use a combibox to set your language - Catalan is available as well as Spanish, so choose whichever is best for you. Ask either on Talk/Discussion pages or on #kde-www if you have any questions.
