This is a brand new error in a system that's been up and running for over a year. After our server administrators ran some Windows updates over the weekend, the Livecycle login page will not load, it flickers between the link to the page and a link starting with https://server/lc/system/sling/cqform/defaultlogin.html....
I tried logging on to system from the server itself with the same results. If I try to log on to the system console, I am presented with a login for the OSGI Administration Console. The default username/password of admin/admin does not work (this is a UAT deployment and as far as I know those were never changed). I also tried karaf/karaf and smx/smx just because I found some posts where those were also used, but they didn't work either. I can log on to the Admin UI just fine.
This is ES4, Version 11.0.0. Any ideas of what I might need to look for to get this system back up and running? I have full access to both the Livecycle server and the Laserfiche server it works with.
