Our help center live installation has broken.  Nothing has been changed on it, but with operators logged in, we can not start chat requests.  It always says all operators are busy.  It does show on/offline correctly and shows the correct department online, but still we can not chat.

On a possibly related note, if I try to start an operator chat I get this error message.  This happened to me also when I tried a clean install.

Incorrect integer value: 'op_8' for column 'chatid' at row 1

INSERT INTO `sessions` (chatid,assignid,departmentid,operatorid,nick,timeo,timeg,alert) VALUES ("op_8", "0", "0", "8", "Tyler", UNIX_TIMESTAMP(), UNIX_TIMESTAMP(), "opchat")

chatid is an integer so why is it trying to put a string in there?

Nope, had to switch to another online help system.
