Follow the same process for registering and configuring iD (`id_key`) and the website/Notes (`oauth_key`), or to save time, simply reuse the same consumer key for each.
+**NOTE:** If you forget to set up OAuth, then you will get an error message similar to `uninitialized constant ActionView::CompiledTemplates::ID_KEY`.

## Troubleshooting
Rails has its own log. To inspect the log, do this:
* Your production database will also need the extensions and functions installed - see [INSTALL.md](INSTALL.md)
* The included version of the map call is quite slow and eats a lot of memory. You should consider using [CGIMap](https://github.com/zerebubuth/openstreetmap-cgimap) instead.
* The included version of the GPX importer is slow and/or completely inoperable. You should consider using [the high-speed GPX importer](https://git.openstreetmap.org/gpx-import.git/).
-* Make sure you precompile the production assets: `RAILS_ENV=production rake assets:precompile`
+* Make sure you generate the i18n files and precompile the production assets: `RAILS_ENV=production rake i18n:js:export assets:precompile`
* Make sure the web server user as well as the rails user can read, write and create directories in `tmp/`.
