Language not changing

Filipe,
The Login With Facebook text is defined in the language files for JFBConnect (in the /languages/xx_YY/xx_YY.com_jfbconnect.ini directory). When you set the pt_BR string, that only controls the language for the social widgets from Facebook (Like, Comment, Fanbox, etc).

Additionally, you shouldn't normally set that language code as JFBConnect will automatically detect the best language based on your default Joomla language as well as if the user has specified their own language.

Hope that helps, but if you need more info, just let me know,
Alex

Glad that worked. If you need anything else, just let us know.

Thanks,
Alex
