Maybe this article will help - Users

Jack - thanks for the response. Unfortunately, the problem isn't with accessing the page where the user is listed, but actually being able to update the Role(s) field. When I access the user I want to change, the role(s) field appears to be 'locked' with no drop down or edit options.

I'm an admin so I believe I should be able to set other users as admins as well, but maybe I'm wrong about that.

That's very strange. Can you provide a full screenshot? Thx.

Jack - here you go. Thanks again

Not sure what happening. Are you not able to Edit the user? The odd thing is that the role is displayed as "Role_User" instead of "User". Maybe there is a bug with the web console.

Try to access the User edit screen via the Admin Bar - http://dev.joget.org/community/display/KBv4/Introducing+the+Admin+Bar

Unfortunately getting the same results no matter which option I use. Thanks again for the help.

Sorry to hear that. Maybe you should contact Joget technical support. BTW, if you are using LDAP/active directory, you can only change your user's role from your directory service. But I have never use LDAP before. So not sure how to help
