How do I...Troubleshoot 'Site settings could not be loaded'?

1. Restoring the config table

If your wiki gets into an irregular state and starts throwing this error:

Your site settings could not be loaded - this could affect your wiki's
operations. Please check to ensure that Dekihost is running.

To troubleshoot, visit /@api/deki/@about - (if your site is http://deki-hayes/, then it'd be http://deki-hayes/@api/deki/@about/)

If you see a 503 Service Temporarily Unavailable, then Dekihost is not running. Try restarting Dekihost: /etc/init.d/dekihost restart (You may also need to restart Apache so that mod_proxy picks up that Dekihost is running). Check errors in /var/log/deki-api.log.
If you see Internal Error (500) - wiki 'default' has failed to initialize or did not start up properly: Initialization exception: Missing api-key for wiki instance Parameter name: api-key then your config table got wiped.
If /@api/deki/@about works, but your site still throws a 500 error when you try to access your site, follow these instructions:
1. Open up LocalSettings.php and find the value associated with $wgDekiApiKey (it will be a long string of text).
2. Access http://your-uri/@api/deki/site/settings?apikey={API-KEY-VALUE-HERE)
3. See what error message is returned - this will help us figure out what the exact problem is
If you only see this error overnight, or after a long period of idle, and then a refresh makes it go away, this is a bug that is being worked on. There are workarounds on the bug report.

Restoring the config table

First, go to /maintenance/tables.sql and search for the phrase "insert into `config`". You'll see a list of SQL inserts. Go into mySQL and run these in your database to repopulate the default values. Then, go to /LocalSettings.php and find the $wgDekiApiKey value. You'll need to manually generate two mySQL insert commands which contains your super-secret API key and the server path to your attachments:

insert into `config` (`config_key`, `config_value`) values('security/api-key','SUPER-SECRET-API-KEY-HERE');
insert into `config` (`config_key`, `config_value`) values('storage/fs/path','/path/to/deki-wiki/attachments');

Note that the path to your attachments will be to the /attachments/ folder in Deki Wiki.

Run this and your config table should be restored. If you can find a way to reproduce config table crashes reliably, please file the issue at our bug tracker: http://bugs.opengarden.org.
