MediaWiki does not save preferences

I've seen this a few times when I've been tinkering with Apache domain name settings. In my case it's been caused by the default server name being http://www.is-beer-a-vegetable.com rather than http://is-beer-a-vegetable.com or vica versa. www or non-www.

This behaviour may be modified by editing Apache settings or possibly by your server provider's admin panel.


It is also worth checking the setting of $wgServer
