Fatal Error (Homepage)

[Veterana]

Hello.
I'm using Nicaw AAC for my website, everything works fine except two things and that is the "Houses" and "Who is online?" pages.

When i try to enter the page called "Houses" i get this error:

Fatal error: Uncaught exception 'DatabaseException'
Message: Your server does not store information on players online state.
File: online-list.php on line: 34
Script was terminated because something unexpected happened. You can report this, if you think it's a bug.

Here is my code for house.php:
