[Mediawiki-l] Simultanious logins on two Mediawikis off the same virtual host?

[Sam Rowe]

Hi,

I upgraded one of our intranet's Mediwikis from 1.3.9 to 1.4.6 tonight
and now I can't stay logged into to it and another Mediawiki on the
same host at the same time.

To try to make that more clear, We have:

https://oursite/wiki1

and 

https://oursite/wiki2

and we used to be able to be logged into both of them (provided that
usernames and passwords were the same!) at the same time. Now we
can't. Any idea what changed or how we can fix it?

Thanks,
Sam
