Just installed, but user login dont work

[munawar5555]

Hi,

 

I have just installed oscommerce at http://marblebusiness.com . installation has been done with sample data.

 

But after installation when I have created new member login, then after putting login info its again sent to Guest first page.

 

Does this is happening due to sample data ? or its any other problem.

 

How I can remove all sample data to run shop for work, I mean manually I have to delete all or any other automatic way ?

 

Please help me to sort out this login problem.

 

Thanks

Munawar
