Cheetah is notoriously hard to debug, and Belchertown is a very complicated skin under the hood. Are you sure you didn't edit the Belchertown skin ?
If not, I'm going to guess here that the driver emitted something that the Belchertown skin didn't expect, or that it did 'not' emit something Belchertown expected. A weewx restart should have cleared that out unless you had a sensor failure or craziness on your WeatherFlow gear, which (unfortunately) happens a lot. First thing to try if it persists is to disable Belchertown and see if that helps. If so, that helps pinpoint where to dig next. To check your WF gear you could always run my standalone python UDP listener (link) <https://github.com/vinceskahan/weatherflow-udp-listener> to try to debug what the WF gear is sending. If you run my listener you need to make sure the weewx WF driver is set with shared_sockets=true 'or' stop weewx while running my listener. My listener has some python prerequisites to add to your system, so read the README carefully and do what it says.
