Thread:Project:Support desk/Session Hijacking error after Update 1.19.14

Hello,

after updating my Intranet-Wiki to Mediawiki 1.19.14 I receive an error on every Password Reset. This can be reproduced by all users: There seems to be a problem with your login session; this action has been canceled as a precaution against session hijacking. Go back to the previous page, reload that page and then try again.

I already tried different things, but can't find a solutiong. My /tmp is writeable. I am using Mediawiki 1.19.14, PHP 5.3.10, MySQL 5.5.35 on an Ubuntu 12.04 LTS. Can anybody please help on this issue?

Thanks in Advance.
