Does anyone know how Mediawiki deals with session cookies. Apparently I am logged out after every browser session. As it is more convenient to be logged in by default, I tried to change the cookie expiration date using the $wgExtendedLoginCookieExpiration hook on the LocalSettings.php. I set it to 30 days. According to this page (https://www.mediawiki.org/wiki/Manual:$wgExtendedLoginCookieExpiration) this should solve the issue. Unfortunately it doesn’t. I am still logged out everytime that I close the browser. Any thoughts on this here? Any users with similar behaviour?
