Unless i could see the rules that have been setup i can't tell you what is blocking what.
Basically once you have setup a firewall script and saved it, and it is blocking ssh/http/https the only way to get into the server is with keyboard and monitor.
You should only have one firewall script running, and because you are using ISPConfig to manage your server you should stay with that.
I know this is not much help now, but what i always do when i am playing around with a firewall on a remote system is setup a cron job script that will reset/flush the firewall rules and open all ports every 5 mins, so if i stuff up something i just have to wait 5 mins for access - and even though i have been using iptables for years now on servers and routers i still stuff it up from time to time.
