I installed Dspace on the 11th of March, 2010 at the University of Ghana. I'm trying to have the system on a Linux box instead of Windows. Everything went on well. I logged into the administrator end and made some changes to the side bar news etc. The changes reflected on the homepage and everything went well. I then shut the machine down. Because i will have to perform some demonstration on Friday, i decided to test the system today and make some few changes. But on the homepage i get an Internal System Error message. Clicking on any of the links still displays the same message. Please help me to fix this. I will be very grateful.
Thanks in advance Below is the first mail i got from the system as the system administrator Date: 3/17/10 12:50 PM Session ID: 4052E39F65C30BF017A143A3C5BBE3A9 -- URL Was: http://dspace.ug.edu.gh:8080/dspace/ -- Method: GET -- Parameters were: Exception: org.postgresql.util.PSQLException: Connection refused.
