I've had MT installed for about a week. It worked fine until yesterday, when I received the following message at the bottom of my login screen.

MT::App::CMS=HASH(0x83a7df4) Use of uninitialized value in split at lib/MT/App.pm line 118.

Also, the login screen appears different now. I can't see the menu bar at the top.

my MT login page

I looked at line 118 of the App.pm file, and this is it:

($user, $pass, $remember) = split /::/, $cookies->{user}->value;

I deleted all of my cookies, then opened my MT login page again, and while the appearance was still messed up, I was able to log in. I then logged out and tried to log in again, but it didn't work. Is there a certain cookie setting that I need to make my login page work properly? Anyone familiar with this? Thanks.

Does anyone know of a fix for this? I keep having to delete my cookies in order to log on. Thanks again.

I finally figured out a solution to this problem, and I think it may be useful for other bloggers who have the Zone Alarm firewall installed. On my privacy options for my login URL, I selected the option to expire all cookies immediately upon receipt. I haven't experienced this problem again since changing this setting.
