Title: Update blockmyaccountfooter.tpl

"Sign out" cannot be translated, remain in English whatever I write into the translation form. Only the title text of the "Sign out" link translates so the problem was with mod='blockmyaccount' - this is blockmyaccountfooter module

with correct mod='' value it works like a charm
regards guys!
