A person renting my home ran a heater in the bedroom with too high of a voltage which caused the outlets on one wall to stop working along with the porch light. What is wrong

The word you are wanting to use is WATTAGE... not voltage.

If that's true you should either find a tripped circuit breaker or a blown fuse.

It is actually your home wiring is the issue not the heater. The heater in question mus be drawing less than 15 amps, if it drew more that that the plug would not fit into your receptacle. If it fits it should work. None from what you said I'd conclude a fuse blew or w circuit breaker popped. Not because the heater is fault but because the circuit is over laoded or you have a short. Do you have fuses or circuit breakers? Popped

What is wrongCould be many things. A tripped breaker or blown fuse is most likely. A bad connection or burned splice is second most.
I agree, the heater likely just exposed a weak point in your wiring. It's not the heater's fault.
