Online store installation problem and errors

[Arne2]

I have just innstalled oscommerce-2.2rc2a in my site. The installation ment well, and all tests were OK.

When i finshed installation the shop appeared and run som security tests against the install folder and my config files. I removed my install folder, ang altered the permissions of confg.php.

 

In the footer however i get this error:

 

 

1062 - Duplicate entry 'ff38b0cc734afa033814091b7826ebc5' for key 1
