Turn of all thirdparty plugins you are using and check whether the problem is solved.

Hello Team,

Thanks for the repsonse.

Tried that ... I can see I have users in STATISTICS but when I go to USER ADMINSTRATION I see none?

Those users need to be validated before they appear in the user administration panel, You can see them in the unvalidated users section, if the uservalidationbyemail plugin is enabled
