Can its possible to show Logout button in Jforum?

[Ulf Dittmer]

Post the full stack trace of the exception, and the code where it occurs. If the line numbers of the stack trace do no match the ones in the code, point out where in the code the exception is thrown, and under which circumstances that code is executed. Also mention which object is null, and what values other related variables have at the moment when the exception occurs: TellTheDetails.
