Boy I don't know how long this has been like this. I just went to one of my sites and signed up as a new user. The new user email I received said that I had a New Private Message and didn't have my password.

I am running the forum plugin and have been for quite awhile. I guess I just never checked.

So I need to put back the new user email for the site. Has anyone else experienced this, I didn't find it on a search, maybe I missed it.

Figured it out, it was the new message from the Messenger Plugin. Turned off Private Message for New Signups and it fixed the problem.
