I have installed SCLongin plugin, but the incorporated Spanish translation is not full in Spanish something keeps in English, and I tried to modify something, but the translation files do not change the text on the plugin
Looking at your page, you're using mod_login (Joomla's core login module), not SCLogin. Attached is the code on your page where you can see the mod_login classes on the html elements.
The translation to spanish is not complete
