I saw this on another site and they seem to think this is a common issue and could cause a fire. What do you folks think? This is scary.

Yup. All the heated bed on the Replicator 1 clones are scary.
You can see my previous posts here admonishing people for running prints unattended, sleeping, not at home. Dont do it.
And most printers can cause a fire. You are extruding a hot flammable material inside a 230 degree tube. IF that tube stops moving, keeps extruding, and that material gets around the extruder, it can catch fire.
Just saying, for safety, people should be careful about all these situations. That having been said, here is some advice on fixing the issue:

What model?? Genuine Creator pro? This is the heated bed connector? On the 2016 version flashforge made a correction to prevent this
This must be an old one or a different model. On mine the cables attach directly to the heater board. There is no sub-board.
It looks like that this is an electrical component that caught fire. All manufacturers of electronic devices have the challenge to make sure to always use original electronic components from their suppliers. The problem is that there are a lot of fake components around - especially in China this is a big issue. The fake components are hard to distinguish from the original. Some of these components are so perfectly made and look like the original. The manufacturer thinks they are original even tests them and finds no problems, maybe only tiny changes in currents occur but still in the tolerance. But after a while of usage these fake components can cause problems. F.E. as seen in the picture. I just assume that this happened. Of course its also possible that wrong or excessive usage of the device could have caused this problem. Lets hope there is still warranty left. Its definately good to notify the manufacturer about this so they can find the source of the problem and solve it.
Very good point, Perry_1, i think its good to mention the safety issue around 3d-printers. Actually even in the FF User-manual it is said not to leave printers unattended while they print. But on the other hand - who can manage to sit next to the printer for hours 
I just bought this one in Aug. of this year from Amazon so I’m hoping its a 2016.
I want to look underneath my printer and check to see if I have this issue but don’t really know what to look for. I bought my FF Creator Pro this Aug. Should I be ok or was the fix just to the bed itself and not underneath? Any help will be appreciated as I don’t want a fire. Thanks, Jim
Contact tang, who sells the FFPros on amazon. He will guide you through how to proceed.
Yes, this is the new connector, and it is less likely to have issues, so I would contact him right away.
He is well know for good support.
I’ll say again that my new FFCP does not have a board that looks like this. The bed heater board plugs directly to the main board.
This most likely is an older model or a different model.

Barring some sort of electronic glitch, the extruders never reach the ignition temperature of any of the polymers used in FDM printing.
Having said that, I have replaced two heat bed connectors on both the Dreamer and the Creator Pro as they were obviously running hot and the connector body was discoloured from the heat. These connections should be checked regularly as they are carrying a significant amount of current.
I have 3 creator pro and run them constantly and have never had this issue. Now that being said watch it happen tomorrow

This plug is behind the heated bed, inside the printer, not at the board.
Must be older models. Maybe they did find an issue and changed the design.
I bet if you have that design you could get with Flashforge and see about getting an updated bed heater that eliminates that board. Might be worth a try.
I have an older creator X. I don’t have that board. The wires burn out on the connector to the heater build plate.
It’s because in the earlier design the wires were too thin. I have kept spare wearing hanesses. I resoldeed the traces on the heater board also. Actually for whatever reason it has not occurred for a long time now. I had to get a new motherboard so maybe it was fixed there. Actually the earlier makerbots had more issues. Flashforge fixed many design issues It’s a better printer for less money.
I used my printer a lot for years now.

Ouch! Funny I see this and today this happened. Mine is on a Dreamer.
Ouch, that sucks! I better go over my FFCP’s and make sure the connections are clean and tight.
