Tech:Troubleshooting

UPDATE THE SAL WITH WHAT YOU DO!

This is a cached copy of the requested page, and may not be up to date (in red)

 * 1) Try running 'rebuildFileCache.php' over the wiki
 * 2) If you get the message saying the wiki does not exist see Renaming a database
 * 3) If the issue persists, fix it!

Mediawiki Magic Word Exceptions
This probably means that the Localisation cache has not updated or someone has enabled an extension on a wiki without it being enabled on extload.
 * 1) Make sure the extension is included on extloadwiki
 * 2) If the issue persists run 'rebuildLocalisationCache.php --wiki extloadwiki'
 * 3) If the issue persists check /var/log/mediawiki/exception.log and fix it!

Unknown database errors everywhere

 * 1) Check the dblist located at "/usr/share/nginx/.orain.org/w/all.dblist" looks correct (this should be a list of database|sitename|wikitags)
 * 2) If this is incorrect and for example the list is HTML then replace the list with the following "metawiki|Orain Meta|"
 * 3) Once this is saved all wikis should be back once the db_list update script is run (which is on a 1 min cron)
 * metawiki
 * 1) With this commit, metawiki will always be online in the event of the dblist becoming corrupted.

Ansible Playbook doesn't appear to be updating

 * 1) Is the cronjob for root still there?
 * 2) Check /var/log/ansible-pull.log for errors
 * 3) Fix them (best bet is probably reverting the changes on github that broke it!)

You changed stuff, stuff broke, you dont know why

 * 1) If it was an extension have you read the documentation and done everything required (update.php, dependancies)
 * 2) Have you done everything documented currently at our readme
 * 3) Try manually flushing the APC cache see here
 * 4) Revert your change! or cry and scream until someone else fixes it

Server/nginx dies or is unresponsive
When this happened the web server seemed to totally inaccessible. Hitting any page would not even show / throw a MW exception, nothing would appear in the nginx, mediawiki or syslogs...
 * 1) rebuild i18n if it works - if not, looks as the nginx error.log or syslogs.
 * 1) rebuild i18n if it works - if not, looks as the nginx error.log or syslogs.
