Hi… I tried to install to know about the reportico, I followed the installation instructions of the site reportico.org (sorry, dont´s send the link because this is my first post 
), I followed and I checked and it is all right, but I am not Can be configured in yii2, it gives the following error “Setting unknown property: yii \ web \ Application :: reportico”. Forgive me but I’m new to the framework.
You should be able to just download and run the installer:

If that does not work, then you need to ask the Reportico guys
