after installation of the complete package (now the installation is successfully without failures .. cool ) and configuration i would add a contract. The page (Whoops, looks like something went wrong.) was displayed.
The LOG is bringing up 1 failure (Integrity constraint violation: 1048 Column 'qos_id' cannot be null ........) so i looked in source code (html end) there is one hidden form field with qos_id which is empty.
Maybe i did something wrong, but doublechecked all things and can't find the issue. Do you have an idea whats wrong?
