Just tested, it worked fine on firefox 3.0.10... untill I'd navigated through maybe 20 changes then I get unable to connect to MySQL database on all the calculator, item and ability sections.
Close firefox, reboot and try to load the page again and it's the plain brown background and unable to connect to MySQL discussed above.
Dunno what happened, new host isn't too draconian with lots of refreshes in a short period or something odd?
