We haven't had a single edible fruit off any of our 5 trees either, but possibly for different reasons. The first crop didn't develop because of the incredibly hard winter we had here, which killed the tiny overwintering fruit, and the second crop is still hard and very small, purely for lack of water. I suspect that your rotten summer has a lot to answer for, this included, but for slightly different reasons. Fig trees generally need warmth and sunshine to perform well.
