I'm using Prestashop 1.5.6 . I translated to spanish the file oneallsociallogin.tpl in the themes/default folder expecting the first form which appears when you log in with Facebook to appear in spanish and it still appears in english. Moreover, I reseted the Prestashop cache thinking that could be the reason and it still is in english. What am I doing wrong? Is there another way to set that form to spanish?
