Clean Install but can't login.

[BAJR]

I know this is one of those  moments.   But here goes.

The install went fine, the database tables were created, the login page came up, it said hello to me and then redirected to teh main page...  but hey...  where was the admin option.   I did a debug mode on it (yup I have been reading many of the other entries before bothering you)  and sure enough...  although when I login in, my status is admin and it knows who I am, when it goes to teh next page,...  bang...  I am back to being a Guest with no rights at all.   I have cleared my cookies, I have banged my head...     but I am lost and have now fallen to my knees.

I have also tried becoming just a normal user..  but that does not login either.

What extra information would you want from me? 

many thanks
