When Everything receives a request, it checks the database for a node of type 'setting' named 'system settings'. This holds default information about the installation.
There are generally only two reasons why you might see this error. Either the database was not started, or there's no 'system settings' node in the database.
You can run Everything from the command line -- just execute the index.pl file. It should give you a similar error message.
The ecore nodeball probably didn't install correctly. Make sure you don't have a root password on the database, then run
make realclean
perl Makefile.PL
make
make install
bin/nbmasta install ecore.nbz everything
That ought to do it.
Update: Oops, there's an ecore directory. Try:
bin/nbmasta install <full path>/<to>/ecore everything |
