Draytek enable web config???

[Cyber-Mav]

hello I got a draytek 2820n the web config has been turned off but I can use telnet to get into it fine. anyone know the command to enable the web config again?

cant factory reset it, its got too big a config on it to loose. I tried the web ports 80 and 8080 but no luck, only telnet works fine but is limiting on what I can do.
any other suggestions?
may have to phone draytek support tomorrow
