There is what looks like a solder bridge between +5 and one of the GND pins causing a short which is why it's burning up. Stop using the board immediately and get someone to clean it up for you properly.
You will cause a lot of damage running it any more so please don't.
There's no solder bridge. It's just light reflecting from the charred PCB.
You really want to try glueing the track down like @RGB said. The problem is that when inserting the jamma connector the lifted track can fold over the neighbouring ground track and then you'll have a bridged connection between 5V and GND.
The proper way to do it would be to:
-remove the original pad and coating over the near by trace
-clean the PCB super well,
-cut a new pad and trace from a copper or gold sheet
-lap solder the new pad onto what's available of the trace
-epoxy the pad down
-clean again
-epoxy over coat the exposed trace
or if it were me I'd just
-clean the PCB super well
-epoxy the lifted trace part
-clean again
