I'm having problems defining the default language in Moodle 1.9.9.
I'm trying to set the pt_utf8 as default language but, after upgrade from version 1.9.5, I get this error:
on the administration menu (Language -> Language Settings -> Default language).
I've tryed re-download of the language pack via interface and manual installation. Neither worked. The packages are there.
The thing more curious is that the admin account is in Portuguese but if I try to change the language, I can only change to English and I can't return to Portuguese. Also I have the French package installed and I have the same problem.
Any ideas?
Thanks in advance,
Nuno
