I am having this problem too. However, it was all working less than two weeks ago.
I started having this problem recently as well. I have done nothing new, but all of a sudden my users don’t receive their passwords when they register. Have you found a solution?
My site uses the geo plugin and young fooks google map plugin. It works well but doesn’t allow for multiple posts on the same location. I am trying to figure a way around this if anyone has any suggestions. thanks.
