WordPress generating bad passwords.

Hello,

I am having an issue with my WP site when people register. They get sent an activation link and then a password. The password always comes back as invalid, even with a copy/paste of it. I tried searching for a solution but anything with “password” is about protecting posts or the site in general.

I have tested this and duplicated it. The only way people can get in after registering is to click the “Lost Password” link. My URL is http://www.massgeocachers.org/ Any ideas? Thanks in advance.
