Hello guys, anyone have a ideia what is that?

DateTime::__construct() [datetime.--construct]: Failed to parse time string (18/04/2013 14:02:19) at position 0 (1): Unexpected character

It happening when I click on new article on K2... just started now.. Im editing the admin page, but have no idea how this started, was working a few moments ago...

In this pt-BR.com_k2.ini so:

K2_DATE="Data"
K2_DATE_FORMAT="%d-%m-%Y - %H:%M"
K2_DATE_FORMAT_LC2="%A, %d %B %Y %H:%M"
K2_DATE_FORMAT_LC="%A, %d %B %Y"

Someone could help me?

Tks
