Thread:Project:Support desk/$wgCookieDomain setting has no effect/reply (2)

First of all do you have any authentication extensions installed. If they handle the cookies themselves, they may override MW's settings for the cookie domain.

MediaWiki should default to not setting a cookie domain whatsoever.

You're sure you are setting $wgCookieDomain at the very bottom of LocalSettings.php?

What does the set-cookie http header that MediaWiki sends look like?
