Hello, I created a new account and liked it to Bnet. After trying to refresh my characters on America, I get the following error:
URL: http://worldoflogs.com/account/battlene ... ns/refresh
I believe this may be because I have one DemonHunter and serverside code may not be updated yet with its definition (thus the null value in 'klass' field). I did a test refreshing my characters on Europe (no DH there) and it updated, but only showed a single character on a US server.
Just as a suggestion: you may want to change your configuration to hide those kind of errors, since it displays a bunch of sensible information.
