[Loris-dev] Unable to Access the Front-end

This sometimes happens if the base path config setting isn't set correctly.
Can you run the SQL: SELECT * from Config WHERE ConfigID=(SELECT ID FROM
ConfigSettings WHERE Name='base');
and see what the result is? Also check if there's a xml tag named <base> in
the config.xml (which would override the database value)
The value should be the directory where you installed LORIS including the
trailing slash. ie `/var/www/loris/` (errors like this sometimes happen if
it's set to `/var/www/loris`)
If that config value is correct, it could also be a filesystem permission
issue. Make sure the files' unix permissions are readable by apache and the
directory permissions leading up to it are all executable by apache
(including the /var and /var/www).
