New sign-up's for our site are no longer working properly.
When a new user signs-up, they have the option to add a new blog at the same time as they sign up on the register page (http://4.biz/register).
However, when they complete their sign-up, they don't get a new blog. Just a profile.
This was working fine on Friday, and nothing has been done to the site since then except for installing 2 plug-ins which have been deleted, but it is still not working properly.
We have tried everything we can think of but it just is not working properly.
Any help would be greatly appreciated!!
