Thread:Project:Support desk/Login not working

Hi, I have recently installed a MediaWiki and everything has been working fine up until now. I suddenly find myself unable to login. The login will correctly recognise if I am using a wrong user or password, or have cookies disabled, but when everything is right, it will just return me to the page I was on before and have me logged in as my IP and not the account I was logging into (tried multiple). From what I can tell, two files are created for the session with the contents: wsUserID|i:1;wsUserName|s:5:"Admin"; and wsLoginToken|s:32:"dc169af1f3daf3b11a6a047e328a6b09";. In my browser I find cookies containing values for mediawiki_fUserID, mediawiki_fUserName and mediawiki_f_session.

I am using: MediaWiki	1.23.9 PHP	5.5.6 (cgi-fcgi) MySQL	5.1.73

Any ideas?
