After upgrading QtCreator from 4.4.1 to version 4.5.0 and then updating Qbs from 1.9.0 to version 1.10.0, an error appeared: "... warning: Module cpp could not be loaded." "Product 'ProductName' had errors and was disabled." It was possible to find the following bugreport QBS-709.
However, the link in the last post is not working. Please help me find a solution of this problem.
