Yes, that you should try with a current version.

MediaWiki 1.19.14 has in fact introduced this bug according to Thread:Project:Support_desk/Session_Hijacking_error_after_Update_1.19.14. What you see is. MediaWiki 1.19.15 should already contain a fix for this! The 1.19 branch has just reached its end of life; anyway, there is a rather current version 1.19.24. If you do not want to go through a number of steps for a MediaWiki upgrade, then you should upgrade your installation to MediaWiki 1.19.24.

By the way, if you have nothing important in that installation yet, you could also just throw it away and start over new with MediaWiki 1.23 - that version has long term support for the next years and in contrast to 1.19 still is supported currently. Or you could do an upgrade to MediaWiki 1.23 - so many possibilities. ;-)
