Hello Aiman, This "Internal System Error" message is just a generic message. To track down the cause of the error, you'll want to look at your dspace log files for any errors noted there (in case of a stack trace send it up to and including any "Caused by" lines).
We've written a "Troubleshoot an error" guide to help you figure out what to look for: https://wiki.duraspace.org/display/DSPACE/Troubleshoot+an+error Once you locate the error message, if you cannot figure out its meaning, you are welcome to send it off to this dspace-tech list. Someone on this list can help you determine what the issue may be.
