After creating community and collection, I tried to submit an item for the
collection. At the last step, once press "I grant the License", 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", always shows up. The log file for dspace is as fellowing:
