Have I over oiled the wok when seasoning
You have used too much oil, or you haven't wiped enough off before heating the pan, the end result is the same.

The best thing to do would be to remove the oil and try again, making sure that you have wiped the wok properly. 
Also, 1) make sure the wok is a bit warm before wiping it with oil (At least if it is cast iron) as this helps it absorb the oil properly; 2) When "baking" the wok in your oven, put it in upside down to prevent the oil "pooling" (And put something in the bottom of your oven to catch any oil that might drip.

Good luck.
