Close a wiki
In order to lock a wiki, do the following:
- Read How to do a configuration change
- Add the wiki to closed.dblist
- Remove the wiki from groupOverrides and groupOverrides2 in wmf-config/InitialiseSettings.php
- If you didn't modify InitialiseSettings.php in the previous step, run touch wmf-config/InitialiseSettings.php on the deployment server to trigger the update of the config cache
