From pRO site:

Ragnaboards is down until further notice.

The announcements made re: change passwords and emails are for those Ragnaboards posters who are using the same user info as their game accounts. If you are one of them, please change your password and email now. If you need further assistance, you may send a ticket through http://levelupsupport.ph or call us at 7519611 from 12 noon to 9pm on weekdays and 12 noon to 6pm on weekends and holidays.

Sorry for the inconvenience.

They’re asking forum members to change their in-game username, password and email if they’re using the same details in the forum. Sounds like a compromised forum database. If that is the case then maybe they didn’t apply the patch on their invision.
