HI, can you add the logs knowge.log and knowageqbeengine.log?

In this way we can have some information about the error
Hi, after the metamodel creation did you press the "generate" button to create the datamart used by the qbe?

Hi, this usually happens when you do not generate the Business Model after saving it from the Web Designer.
