Error on upgrade to version from 1.4.3 to 1.5

Hi guys,

I want to upgrade to 1.5.4 but i tought it was better to first upgrade to 1.5 so i could follow all the update instructions.

When i go to /index.php/setup i get an error. Can someone help me please?

No. Please use the newest version to upgrade from 1.4 to 1.5.
