Hi guys.
Please, our dspace is now up but there is a problem with user login. Whenever
an authourised user wants to login, it displays this error:
DSpace at University of JOS >
Internal System Error
The
system has experienced an internal error. Please try to do what you
were doing again, and if the problem persists, please contact us so we
can fix the problem.
If one then clicks on "Leave a message for the DSpace at University of JOS
administrators.", it sends the following error to the administrators:
-- URL Was: http://dspace.unijos.edu.ng/password-login
-- Method: POST
-- Parameters were:
-- login_email: "f...@unijos.edu.ng"
-- login_password: *not logged*
-- login_submit: "Log In"
Exception:
java.lang.NullPointerException
