BuddyPress.org

My registration page comes up. I enter the data and hit the complete sign up button. At that point the page is still there but my passwords have been cleared. I re-enter the passwords and hit the complete sign up button and then it does the registration. Anyone know why this might be happening? I am on 2.7.0 buddypress, using the evolve plus theme. It has worked in the past on this theme so i have either changed a setting that i did not understand or a plugin may be conflicting. I have the mailchimp plugin with buddypress integration set but i have tried to deactivate that and it has no affect. Anyone experienced this and have a solution?
