I've checked your registration page and pop-up and clearly don't see any error message. Maybe reCaptcha is causing problems, do you use reCaptcha ? If yes please check whether it is configured properly in plugin settings and in Joomla global configuration.

When you click into create account. show the popup with the error message with all browsers

SOLUÇÃO:

Passos:

1. Vá em: administrator->language->pt-BR -> pt-BR.com_k2.ini

2. No arquivo pt-BR.com_k2.ini (do diretório 'administrator'), pesquise por: K2_J16_DATE_FORMAT_CALENDAR="d/m/Y H:i:s"

3. Altere para: K2_J16_DATE_FORMAT_CALENDAR="d-m-Y H:i:s"

Maybe this was just a problem with missing translation. You can easily check this by switch to default english language.
