Trim the trace that's sticking up, install the new cap, and run a piece of wire from the capacitor lead terminal to the lead of the white power resistor.

Is this a double sided PCB, with copper traces on both the component side and the underside?

Check for damaged traces on the underside. Repair if necessary.

Yes , on the other side looks good............ But my concern is when I touch that gold sheet looks like a toy (not professional), I don't know , but because they not doing something better ......as a board of glass epoxy with Turret Lugs ; I distrust of the performance that can take the PCB.
