Tomcat 500 error creating new user

[colinmain]

I'm getting a tomcat 500 error when I try to create a new user. I had thought I might have some odd characters in one of the fields but this does not appear to be the case. Please can you try to help point me in the right direction?

The message is as follows:

[junoyoon]

Could you tell me which version of ngrinder controller you're using?

[colinmain]

This is on 3.2.1 but has not happened before - or since - this.
I would not treat it as a high priority unless you have seen it elsewhere.

Many thanks,

Colin

I can not reproduce this.

Could you just log out clearly and log in again?
Then clear the browser cookie.
And.. restart the ngrinder controller.

It might help you to resolve this issue.
