My moodle has been set up in Portuguese and not yours because it is now always in English.
I already changed the options but always keeps the same.
They can help.Podes ser mais específico?
O que te aparece em http://yourdomain/moodle/admin/settings.php?section=langsettings?
Na tabela mdl_config o que te aparece no registo lang? Está pt?

Can you be more specific?
What appears to you at http: //yourdomain/moodle/admin/settings.php? Section = langsettings?
In the mdl_config table what appears to you in the lang register? Is it pt?
