Incorrect displaying of translated phrases
 

Hi all,

I have a board in spanish and I have the correct translations for every month of the year:

Code:
$vbphrase[january] -> $vbphrase[enero]
$vbphrase[february] -> $vbphrase[febrero]
$vbphrase[march] -> $vbphrase[marzo]
..............
but still... when displaying user's birthday dates, the month appears in english instead of spanish but only when displaying. When a new user fills the registration form, the month does appear in spanish... wth???

Thanks in advance,
