Thanks for your reply,

I tried that, also retried again now, the same error
"500 Internal server error
Internal server error."
All links to user list, gives error including those under
control panel/user management
control panel/list management
control panel/list management/member list (clicking the link or choosing edit)

clicking on "new" also comes up with 500 error
I can copy but the copy also exhibits same error behavior - cant edit, cant open

I have ran the user database tools under tools, all came up green- no error detected

have tried all i can, including head scratching, hair pulling and screaming!
I can give you access if you want to check it yourself?

Disable non-core CB plugins 1 by 1 within CB > Plugin Management and retry to see if it's something installed. Aside from that I don't know what to tell you beyond contact your host if you're unable to debug a server error. Probably something you've installed is causing a serious conflict.
