I installed Ninja board and got the "The Ninja Framework component (com_ninja) is required for this component to run" error. After browsing the forums I ran across this thread and followed its instructions. I tried installing separately the com_ninja.zip package and then I got the white screen of death - now I don't have any access to the admin panel and the website crashed, giving a server error message.
Any ideas what went wrong or what can I do to fix it?
Tomorrow morning I'll be able to call our sysadmin for help, but I was hoping I could manage this on my own somehow, best before tomorrow.
