Setting language on “Dashboard>Settings>General>Site Language”.
WP language file is Ok. If I uninstall bp and set wp to portuguese it just runs fine.
If I try to install bp with the language set to portuguese, the error occours during bp activation.

I worked aroung seting the language to english and was able to install/activate bp.
After bp activation, I uploaded brazilian portuguese translation files (which are outdated) and set wp to portuguese.
Error happens after the “Save Changes” on the “Dashboard>Settings>General>Site Language” page.
