Also I have tried to import old v1.5.5 configuration and configuration group in the new db of v1.5.6.

That gived 17 errors (in short there should be one more column wich is missing and that is why i aded one more ",NULL," at the end)
When I aded that ",NULL," the module worked exept the part i mentioned above.

There is something more that needs to be aded and its obvious not ,NULL, but i dont know what, maybe "1" or "0" or something elese i dont know what ,

Thank you for your help!
