Keep on getting "Please activate" message

Hi all

I keep on getting this page:

http://morebusinessalliance.biz/activate

I am using the Social Theme and there is really no reason why this should happen. My users get the activation email just fine, they click the activation link and then gets taken to the page above...

But they can log in and start using the platform just fine, no need for the activation key, there is no activaiton key sent or anything. It happens with most people, but some do not get it...

I am using the latest BP version.
