If you can’t light your candle wick because it’s too short, try to take a little bit of the wax away from around the candle. You could scrape this away, or soften up the surrounding wax using a blow drier or candle lighter. Be careful doing this because you’ll have the flame at different angles. Remove the wax around the wick using a Q-tip or tweezers, or by pouring. Then light the wick and it should burn down like it used to. Let it burn for 30 minutes to establish a pool of melted wax around it.
