in the older version you cannot manage alert via web-based interface even though it says "manage". You need to do it through "Alerts Management" app which is sitting on your server itself. There are two of them there - "Advanced Alert Manager" and "Basic Alert Manager"
You should not use Basic Alert Manager anymore. Only use Advanced Alert Manager.
Why do you want to use Basic Alert Manager?
I'm still running the same versions as you.
