The most common location for the configuration files will be /etc/fusionforge/config.ini and the files under /etc/fusionforge/config.ini.d/*. Note that in that directory, only files with extension ".ini" and those without an extension will be taken into account (so that files such as foo.old, foo.bak and so on are ignored). Note also that you can reference other files and directories by adding extra_config_files and extra_config_dirs variables (see below) to one of the standard files.
If you're upgrading from a version of FusionForge before 5.1, the migrate-to-ini-files.sh script should take care of migrating your setting from the previous system. In this case, you'll get /etc/fusionforge/config.ini.d/zzz-migrated-old-config and /etc/fusionforge/config.ini.d/zzz-migrated-old-secrets.
The config files are standard *.ini files as widely used in Windows, PHP and other systems. It's basically a key/value store, where there are different namespaces for the keys called sections. The variables controlling the features in the core of FusionForge are in section [core], the variables controlling the "extratabs" plugin are in section [extratabs], and so on.
For values storing a string, quoting is required when the string contains spaces, or quotes, or any kind of special character. For boolean variables, some flexibility is available, and the value can be stored as "true", "1", "on", "yes", "false", "0", "off" or "no".
Comments start with a semicolon and extend to the end of the line. Empty lines are ignored.
Variables can reference one another with the "$section/variable" syntax. For instance, in section [scmsvn], the default value for repos_path is defined in relation to the value of chroot in section [core] with the following syntax: repos_path = "$core/chroot/scmrepos/svn". If the chroot variable is set to /srv/fusionforge/chroot, then the repos_path value will automatically contain /srv/fusionforge/chroot/scmrepos/svn; other variables will also be updated accordingly, without needing to set their individual values in the config files.
- allow_project_without_template (boolean): allow users to not choose a template project when registering a new project. If false, then new projects will always be based on a template (unless no such template exists, of course).

- database_user: user for the database connection.
- extra_config_dirs: directories containing other configuration files to read.
- extra_config_files: other individual configuration files to read.
- forge_name: the "visible name" of the forge. Used in webpage titles, in emails, in feedback messages, and so on. Could be set to "YourCompanyForge" for instance.
