since there is no more admin table in D7, here is what I had to do:
1- make a new profile type called "admin" and allow ALL actions
2- make a new user, regular sign up
3- set that user to the "admin" membership
4- turn off admin memberships
5- go to database and change their ROLE field in the PROFILES TABLE to =3
6- copy and paste the same SALT field
7- delete the cache files, MANUALLY
done...
to Boonex: can we please have a button for this in the admin dashboard?
