This error is received when the logged in user does not have enough permissions to make changes to the POS Configurator. Please ensure that a user with admin privileges is logged in to be able to edit/verify the interfaces, discount screens, check trailers etc. under the POS configurator.
Note: There could be multiple user profiles on the back office. Punchh might have been installed using a user with admin permissions but the PC might currently be logged in with a different user profile.
